+// Public domain.
+//
+// NOTE: Do not protect this header against multiple inclusion.  Doing
+// so can have subtle side-effects due to header file inclusion order
+// and testing of e.g. _POSIX_SOURCE vs. _POSIX_C_SOURCE.  Instead,
+// protect each CPP macro that we want to supply.
+
+// Feature-test macros are defined by several standards, and allow an
+// application to specify what symbols they want the system headers to
+// expose, and hence what standard they want them to conform to.
+// There are two classes of feature-test macros.  The first class
+// specify complete standards, and if one of these is defined, header
+// files will try to conform to the relevant standard.  They are:
+//
+// ANSI macros:
+// _ANSI_SOURCE			ANSI C89
+//
+// POSIX macros:
+// _POSIX_SOURCE == 1		IEEE Std 1003.1 (version?)
+// _POSIX_C_SOURCE == 1		IEEE Std 1003.1-1990
+// _POSIX_C_SOURCE == 2		IEEE Std 1003.2-1992
+// _POSIX_C_SOURCE == 199309L	IEEE Std 1003.1b-1993
+// _POSIX_C_SOURCE == 199506L	ISO/IEC 9945-1:1996
+// _POSIX_C_SOURCE == 200112L	IEEE Std 1003.1-2001
+// _POSIX_C_SOURCE == 200809L   IEEE Std 1003.1-2008
+//
+// X/Open macros:
+// _XOPEN_SOURCE		System Interfaces and Headers, Issue 4, Ver 2
+// _XOPEN_SOURCE_EXTENDED == 1	XSH4.2 UNIX extensions
+// _XOPEN_SOURCE == 500		System Interfaces and Headers, Issue 5
+// _XOPEN_SOURCE == 520		Networking Services (XNS), Issue 5.2
+// _XOPEN_SOURCE == 600		IEEE Std 1003.1-2001, XSI option
+// _XOPEN_SOURCE == 700		IEEE Std 1003.1-2008, XSI option
+//
+// NetBSD macros:
+// _NETBSD_SOURCE == 1		Make all NetBSD features available.
+//
+// If more than one of these "major" feature-test macros is defined,
+// then the set of facilities provided (and namespace used) is the
+// union of that specified by the relevant standards, and in case of
+// conflict, the earlier standard in the above list has precedence (so
+// if both _POSIX_C_SOURCE and _NETBSD_SOURCE are defined, the version
+// of rename() that's used is the POSIX one).  If none of the "major"
+// feature-test macros is defined, _NETBSD_SOURCE is assumed.
+//
+// There are also "minor" feature-test macros, which enable extra
+// functionality in addition to some base standard.  They should be
+// defined along with one of the "major" macros.  The "minor" macros
+// are:
+//
+// _REENTRANT
+// _ISOC99_SOURCE
+// _ISOC11_SOURCE
+// _LARGEFILE_SOURCE		Large File Support
+//		<http://ftp.sas.com/standards/large.file/x_open.20Mar96.html>

+// Public domain.
+//
+// NOTE: Do not protect this header against multiple inclusion.  Doing
+// so can have subtle side-effects due to header file inclusion order
+// and testing of e.g. _POSIX_SOURCE vs. _POSIX_C_SOURCE.  Instead,
+// protect each CPP macro that we want to supply.
+
+// Feature-test macros are defined by several standards, and allow an
+// application to specify what symbols they want the system headers to
+// expose, and hence what standard they want them to conform to.
+// There are two classes of feature-test macros.  The first class
+// specify complete standards, and if one of these is defined, header
+// files will try to conform to the relevant standard.  They are:
+//
+// ANSI macros:
+// _ANSI_SOURCE			ANSI C89
+//
+// POSIX macros:
+// _POSIX_SOURCE == 1		IEEE Std 1003.1 (version?)
+// _POSIX_C_SOURCE == 1		IEEE Std 1003.1-1990
+// _POSIX_C_SOURCE == 2		IEEE Std 1003.2-1992
+// _POSIX_C_SOURCE == 199309L	IEEE Std 1003.1b-1993
+// _POSIX_C_SOURCE == 199506L	ISO/IEC 9945-1:1996
+// _POSIX_C_SOURCE == 200112L	IEEE Std 1003.1-2001
+// _POSIX_C_SOURCE == 200809L   IEEE Std 1003.1-2008
+//
+// X/Open macros:
+// _XOPEN_SOURCE		System Interfaces and Headers, Issue 4, Ver 2
+// _XOPEN_SOURCE_EXTENDED == 1	XSH4.2 UNIX extensions
+// _XOPEN_SOURCE == 500		System Interfaces and Headers, Issue 5
+// _XOPEN_SOURCE == 520		Networking Services (XNS), Issue 5.2
+// _XOPEN_SOURCE == 600		IEEE Std 1003.1-2001, XSI option
+// _XOPEN_SOURCE == 700		IEEE Std 1003.1-2008, XSI option
+//
+// NetBSD macros:
+// _NETBSD_SOURCE == 1		Make all NetBSD features available.
+//
+// If more than one of these "major" feature-test macros is defined,
+// then the set of facilities provided (and namespace used) is the
+// union of that specified by the relevant standards, and in case of
+// conflict, the earlier standard in the above list has precedence (so
+// if both _POSIX_C_SOURCE and _NETBSD_SOURCE are defined, the version
+// of rename() that's used is the POSIX one).  If none of the "major"
+// feature-test macros is defined, _NETBSD_SOURCE is assumed.
+//
+// There are also "minor" feature-test macros, which enable extra
+// functionality in addition to some base standard.  They should be
+// defined along with one of the "major" macros.  The "minor" macros
+// are:
+//
+// _REENTRANT
+// _ISOC99_SOURCE
+// _ISOC11_SOURCE
+// _LARGEFILE_SOURCE		Large File Support
+//		<http://ftp.sas.com/standards/large.file/x_open.20Mar96.html>
+
+// Definitions for byte order, according to byte significance from low
+// address to high.
+
+// C-family endian-ness definitions

+//
+// NOTE: Do not protect this header against multiple inclusion.  Doing
+// so can have subtle side-effects due to header file inclusion order
+// and testing of e.g. _POSIX_SOURCE vs. _POSIX_C_SOURCE.  Instead,
+// protect each CPP macro that we want to supply.
+
+// Feature-test macros are defined by several standards, and allow an
+// application to specify what symbols they want the system headers to
+// expose, and hence what standard they want them to conform to.
+// There are two classes of feature-test macros.  The first class
+// specify complete standards, and if one of these is defined, header
+// files will try to conform to the relevant standard.  They are:
+//
+// ANSI macros:
+// _ANSI_SOURCE			ANSI C89
+//
+// POSIX macros:
+// _POSIX_SOURCE == 1		IEEE Std 1003.1 (version?)
+// _POSIX_C_SOURCE == 1		IEEE Std 1003.1-1990
+// _POSIX_C_SOURCE == 2		IEEE Std 1003.2-1992
+// _POSIX_C_SOURCE == 199309L	IEEE Std 1003.1b-1993
+// _POSIX_C_SOURCE == 199506L	ISO/IEC 9945-1:1996
+// _POSIX_C_SOURCE == 200112L	IEEE Std 1003.1-2001
+// _POSIX_C_SOURCE == 200809L   IEEE Std 1003.1-2008
+//
+// X/Open macros:
+// _XOPEN_SOURCE		System Interfaces and Headers, Issue 4, Ver 2
+// _XOPEN_SOURCE_EXTENDED == 1	XSH4.2 UNIX extensions
+// _XOPEN_SOURCE == 500		System Interfaces and Headers, Issue 5
+// _XOPEN_SOURCE == 520		Networking Services (XNS), Issue 5.2
+// _XOPEN_SOURCE == 600		IEEE Std 1003.1-2001, XSI option
+// _XOPEN_SOURCE == 700		IEEE Std 1003.1-2008, XSI option
+//
+// NetBSD macros:
+// _NETBSD_SOURCE == 1		Make all NetBSD features available.
+//
+// If more than one of these "major" feature-test macros is defined,
+// then the set of facilities provided (and namespace used) is the
+// union of that specified by the relevant standards, and in case of
+// conflict, the earlier standard in the above list has precedence (so
+// if both _POSIX_C_SOURCE and _NETBSD_SOURCE are defined, the version
+// of rename() that's used is the POSIX one).  If none of the "major"
+// feature-test macros is defined, _NETBSD_SOURCE is assumed.
+//
+// There are also "minor" feature-test macros, which enable extra
+// functionality in addition to some base standard.  They should be
+// defined along with one of the "major" macros.  The "minor" macros
+// are:
+//
+// _REENTRANT
+// _ISOC99_SOURCE
+// _ISOC11_SOURCE
+// _LARGEFILE_SOURCE		Large File Support
+//		<http://ftp.sas.com/standards/large.file/x_open.20Mar96.html>

+// Arch-specific definitions.  Each architecture must define the following
+//    macros to define the expected sizes of pthread data types:
+//
+//    __SIZEOF_PTHREAD_ATTR_T        - size of pthread_attr_t.
+//    __SIZEOF_PTHREAD_MUTEX_T       - size of pthread_mutex_t.
+//    __SIZEOF_PTHREAD_MUTEXATTR_T   - size of pthread_mutexattr_t.

+//    __SIZEOF_PTHREAD_RWLOCKATTR_T  - size of pthread_rwlockattr_t.
+//    __SIZEOF_PTHREAD_BARRIER_T     - size of pthread_barrier_t.
+//    __SIZEOF_PTHREAD_BARRIERATTR_T - size of pthread_barrierattr_t.
+//
+//    The additional macro defines any constraint for the lock alignment
+//    inside the thread structures:
+//
+//    __LOCK_ALIGNMENT - for internal lock/futex usage.
+//
+//    Same idea but for the once locking primitive:

+// Public domain.
+//
+// NOTE: Do not protect this header against multiple inclusion.  Doing
+// so can have subtle side-effects due to header file inclusion order
+// and testing of e.g. _POSIX_SOURCE vs. _POSIX_C_SOURCE.  Instead,
+// protect each CPP macro that we want to supply.
+
+// Feature-test macros are defined by several standards, and allow an
+// application to specify what symbols they want the system headers to
+// expose, and hence what standard they want them to conform to.
+// There are two classes of feature-test macros.  The first class
+// specify complete standards, and if one of these is defined, header
+// files will try to conform to the relevant standard.  They are:
+//
+// ANSI macros:
+// _ANSI_SOURCE			ANSI C89
+//
+// POSIX macros:
+// _POSIX_SOURCE == 1		IEEE Std 1003.1 (version?)
+// _POSIX_C_SOURCE == 1		IEEE Std 1003.1-1990
+// _POSIX_C_SOURCE == 2		IEEE Std 1003.2-1992
+// _POSIX_C_SOURCE == 199309L	IEEE Std 1003.1b-1993
+// _POSIX_C_SOURCE == 199506L	ISO/IEC 9945-1:1996
+// _POSIX_C_SOURCE == 200112L	IEEE Std 1003.1-2001
+// _POSIX_C_SOURCE == 200809L   IEEE Std 1003.1-2008
+//
+// X/Open macros:
+// _XOPEN_SOURCE		System Interfaces and Headers, Issue 4, Ver 2
+// _XOPEN_SOURCE_EXTENDED == 1	XSH4.2 UNIX extensions
+// _XOPEN_SOURCE == 500		System Interfaces and Headers, Issue 5
+// _XOPEN_SOURCE == 520		Networking Services (XNS), Issue 5.2
+// _XOPEN_SOURCE == 600		IEEE Std 1003.1-2001, XSI option
+// _XOPEN_SOURCE == 700		IEEE Std 1003.1-2008, XSI option
+//
+// NetBSD macros:
+// _NETBSD_SOURCE == 1		Make all NetBSD features available.
+//
+// If more than one of these "major" feature-test macros is defined,
+// then the set of facilities provided (and namespace used) is the
+// union of that specified by the relevant standards, and in case of
+// conflict, the earlier standard in the above list has precedence (so
+// if both _POSIX_C_SOURCE and _NETBSD_SOURCE are defined, the version
+// of rename() that's used is the POSIX one).  If none of the "major"
+// feature-test macros is defined, _NETBSD_SOURCE is assumed.
+//
+// There are also "minor" feature-test macros, which enable extra
+// functionality in addition to some base standard.  They should be
+// defined along with one of the "major" macros.  The "minor" macros
+// are:
+//
+// _REENTRANT
+// _ISOC99_SOURCE
+// _ISOC11_SOURCE
+// _LARGEFILE_SOURCE		Large File Support
+//		<http://ftp.sas.com/standards/large.file/x_open.20Mar96.html>

+// Public domain.
+//
+// NOTE: Do not protect this header against multiple inclusion.  Doing
+// so can have subtle side-effects due to header file inclusion order
+// and testing of e.g. _POSIX_SOURCE vs. _POSIX_C_SOURCE.  Instead,
+// protect each CPP macro that we want to supply.
+
+// Feature-test macros are defined by several standards, and allow an
+// application to specify what symbols they want the system headers to
+// expose, and hence what standard they want them to conform to.
+// There are two classes of feature-test macros.  The first class
+// specify complete standards, and if one of these is defined, header
+// files will try to conform to the relevant standard.  They are:
+//
+// ANSI macros:
+// _ANSI_SOURCE			ANSI C89
+//
+// POSIX macros:
+// _POSIX_SOURCE == 1		IEEE Std 1003.1 (version?)
+// _POSIX_C_SOURCE == 1		IEEE Std 1003.1-1990
+// _POSIX_C_SOURCE == 2		IEEE Std 1003.2-1992
+// _POSIX_C_SOURCE == 199309L	IEEE Std 1003.1b-1993
+// _POSIX_C_SOURCE == 199506L	ISO/IEC 9945-1:1996
+// _POSIX_C_SOURCE == 200112L	IEEE Std 1003.1-2001
+// _POSIX_C_SOURCE == 200809L   IEEE Std 1003.1-2008
+//
+// X/Open macros:
+// _XOPEN_SOURCE		System Interfaces and Headers, Issue 4, Ver 2
+// _XOPEN_SOURCE_EXTENDED == 1	XSH4.2 UNIX extensions
+// _XOPEN_SOURCE == 500		System Interfaces and Headers, Issue 5
+// _XOPEN_SOURCE == 520		Networking Services (XNS), Issue 5.2
+// _XOPEN_SOURCE == 600		IEEE Std 1003.1-2001, XSI option
+// _XOPEN_SOURCE == 700		IEEE Std 1003.1-2008, XSI option
+//
+// NetBSD macros:
+// _NETBSD_SOURCE == 1		Make all NetBSD features available.
+//
+// If more than one of these "major" feature-test macros is defined,
+// then the set of facilities provided (and namespace used) is the
+// union of that specified by the relevant standards, and in case of
+// conflict, the earlier standard in the above list has precedence (so
+// if both _POSIX_C_SOURCE and _NETBSD_SOURCE are defined, the version
+// of rename() that's used is the POSIX one).  If none of the "major"
+// feature-test macros is defined, _NETBSD_SOURCE is assumed.
+//
+// There are also "minor" feature-test macros, which enable extra
+// functionality in addition to some base standard.  They should be
+// defined along with one of the "major" macros.  The "minor" macros
+// are:
+//
+// _REENTRANT
+// _ISOC99_SOURCE
+// _ISOC11_SOURCE
+// _LARGEFILE_SOURCE		Large File Support
+//		<http://ftp.sas.com/standards/large.file/x_open.20Mar96.html>
+
+// Definitions for byte order, according to byte significance from low
+// address to high.

+// C-family endian-ness definitions

+// ANSI macros:

+//
+// POSIX macros:
+// _POSIX_SOURCE == 1		IEEE Std 1003.1 (version?)
+// _POSIX_C_SOURCE == 1		IEEE Std 1003.1-1990

+//
+// NOTE: Do not protect this header against multiple inclusion.  Doing
+// so can have subtle side-effects due to header file inclusion order
+// and testing of e.g. _POSIX_SOURCE vs. _POSIX_C_SOURCE.  Instead,
+// protect each CPP macro that we want to supply.
+
+// Feature-test macros are defined by several standards, and allow an
+// application to specify what symbols they want the system headers to
+// expose, and hence what standard they want them to conform to.
+// There are two classes of feature-test macros.  The first class
+// specify complete standards, and if one of these is defined, header
+// files will try to conform to the relevant standard.  They are:
+//
+// ANSI macros:
+// _ANSI_SOURCE			ANSI C89
+//
+// POSIX macros:
+// _POSIX_SOURCE == 1		IEEE Std 1003.1 (version?)
+// _POSIX_C_SOURCE == 1		IEEE Std 1003.1-1990
+// _POSIX_C_SOURCE == 2		IEEE Std 1003.2-1992
+// _POSIX_C_SOURCE == 199309L	IEEE Std 1003.1b-1993
+// _POSIX_C_SOURCE == 199506L	ISO/IEC 9945-1:1996
+// _POSIX_C_SOURCE == 200112L	IEEE Std 1003.1-2001
+// _POSIX_C_SOURCE == 200809L   IEEE Std 1003.1-2008
+//
+// X/Open macros:
+// _XOPEN_SOURCE		System Interfaces and Headers, Issue 4, Ver 2
+// _XOPEN_SOURCE_EXTENDED == 1	XSH4.2 UNIX extensions
+// _XOPEN_SOURCE == 500		System Interfaces and Headers, Issue 5
+// _XOPEN_SOURCE == 520		Networking Services (XNS), Issue 5.2
+// _XOPEN_SOURCE == 600		IEEE Std 1003.1-2001, XSI option
+// _XOPEN_SOURCE == 700		IEEE Std 1003.1-2008, XSI option
+//
+// NetBSD macros:
+// _NETBSD_SOURCE == 1		Make all NetBSD features available.
+//
+// If more than one of these "major" feature-test macros is defined,
+// then the set of facilities provided (and namespace used) is the
+// union of that specified by the relevant standards, and in case of
+// conflict, the earlier standard in the above list has precedence (so
+// if both _POSIX_C_SOURCE and _NETBSD_SOURCE are defined, the version
+// of rename() that's used is the POSIX one).  If none of the "major"
+// feature-test macros is defined, _NETBSD_SOURCE is assumed.
+//
+// There are also "minor" feature-test macros, which enable extra
+// functionality in addition to some base standard.  They should be
+// defined along with one of the "major" macros.  The "minor" macros
+// are:
+//
+// _REENTRANT
+// _ISOC99_SOURCE
+// _ISOC11_SOURCE
+// _LARGEFILE_SOURCE		Large File Support

+// Public domain.
+//
+// NOTE: Do not protect this header against multiple inclusion.  Doing
+// so can have subtle side-effects due to header file inclusion order
+// and testing of e.g. _POSIX_SOURCE vs. _POSIX_C_SOURCE.  Instead,
+// protect each CPP macro that we want to supply.
+
+// Feature-test macros are defined by several standards, and allow an
+// application to specify what symbols they want the system headers to
+// expose, and hence what standard they want them to conform to.
+// There are two classes of feature-test macros.  The first class
+// specify complete standards, and if one of these is defined, header
+// files will try to conform to the relevant standard.  They are:
+//
+// ANSI macros:
+// _ANSI_SOURCE			ANSI C89
+//
+// POSIX macros:
+// _POSIX_SOURCE == 1		IEEE Std 1003.1 (version?)
+// _POSIX_C_SOURCE == 1		IEEE Std 1003.1-1990
+// _POSIX_C_SOURCE == 2		IEEE Std 1003.2-1992
+// _POSIX_C_SOURCE == 199309L	IEEE Std 1003.1b-1993
+// _POSIX_C_SOURCE == 199506L	ISO/IEC 9945-1:1996
+// _POSIX_C_SOURCE == 200112L	IEEE Std 1003.1-2001
+// _POSIX_C_SOURCE == 200809L   IEEE Std 1003.1-2008
+//
+// X/Open macros:
+// _XOPEN_SOURCE		System Interfaces and Headers, Issue 4, Ver 2
+// _XOPEN_SOURCE_EXTENDED == 1	XSH4.2 UNIX extensions
+// _XOPEN_SOURCE == 500		System Interfaces and Headers, Issue 5
+// _XOPEN_SOURCE == 520		Networking Services (XNS), Issue 5.2
+// _XOPEN_SOURCE == 600		IEEE Std 1003.1-2001, XSI option
+// _XOPEN_SOURCE == 700		IEEE Std 1003.1-2008, XSI option
+//
+// NetBSD macros:
+// _NETBSD_SOURCE == 1		Make all NetBSD features available.
+//
+// If more than one of these "major" feature-test macros is defined,
+// then the set of facilities provided (and namespace used) is the
+// union of that specified by the relevant standards, and in case of
+// conflict, the earlier standard in the above list has precedence (so
+// if both _POSIX_C_SOURCE and _NETBSD_SOURCE are defined, the version
+// of rename() that's used is the POSIX one).  If none of the "major"
+// feature-test macros is defined, _NETBSD_SOURCE is assumed.
+//
+// There are also "minor" feature-test macros, which enable extra
+// functionality in addition to some base standard.  They should be
+// defined along with one of the "major" macros.  The "minor" macros
+// are:
+//
+// _REENTRANT
+// _ISOC99_SOURCE
+// _ISOC11_SOURCE
+// _LARGEFILE_SOURCE		Large File Support
+//		<http://ftp.sas.com/standards/large.file/x_open.20Mar96.html>
+
+// Definitions for byte order, according to byte significance from low
+// address to high.

+// Public domain.
+//
+// NOTE: Do not protect this header against multiple inclusion.  Doing
+// so can have subtle side-effects due to header file inclusion order
+// and testing of e.g. _POSIX_SOURCE vs. _POSIX_C_SOURCE.  Instead,
+// protect each CPP macro that we want to supply.
+
+// Feature-test macros are defined by several standards, and allow an
+// application to specify what symbols they want the system headers to
+// expose, and hence what standard they want them to conform to.
+// There are two classes of feature-test macros.  The first class
+// specify complete standards, and if one of these is defined, header
+// files will try to conform to the relevant standard.  They are:
+//
+// ANSI macros:
+// _ANSI_SOURCE			ANSI C89
+//
+// POSIX macros:
+// _POSIX_SOURCE == 1		IEEE Std 1003.1 (version?)
+// _POSIX_C_SOURCE == 1		IEEE Std 1003.1-1990
+// _POSIX_C_SOURCE == 2		IEEE Std 1003.2-1992
+// _POSIX_C_SOURCE == 199309L	IEEE Std 1003.1b-1993
+// _POSIX_C_SOURCE == 199506L	ISO/IEC 9945-1:1996
+// _POSIX_C_SOURCE == 200112L	IEEE Std 1003.1-2001
+// _POSIX_C_SOURCE == 200809L   IEEE Std 1003.1-2008
+//
+// X/Open macros:
+// _XOPEN_SOURCE		System Interfaces and Headers, Issue 4, Ver 2
+// _XOPEN_SOURCE_EXTENDED == 1	XSH4.2 UNIX extensions
+// _XOPEN_SOURCE == 500		System Interfaces and Headers, Issue 5
+// _XOPEN_SOURCE == 520		Networking Services (XNS), Issue 5.2
+// _XOPEN_SOURCE == 600		IEEE Std 1003.1-2001, XSI option
+// _XOPEN_SOURCE == 700		IEEE Std 1003.1-2008, XSI option
+//
+// NetBSD macros:
+// _NETBSD_SOURCE == 1		Make all NetBSD features available.
+//
+// If more than one of these "major" feature-test macros is defined,
+// then the set of facilities provided (and namespace used) is the
+// union of that specified by the relevant standards, and in case of
+// conflict, the earlier standard in the above list has precedence (so
+// if both _POSIX_C_SOURCE and _NETBSD_SOURCE are defined, the version
+// of rename() that's used is the POSIX one).  If none of the "major"
+// feature-test macros is defined, _NETBSD_SOURCE is assumed.
+//
+// There are also "minor" feature-test macros, which enable extra
+// functionality in addition to some base standard.  They should be
+// defined along with one of the "major" macros.  The "minor" macros
+// are:
+//
+// _REENTRANT
+// _ISOC99_SOURCE
+// _ISOC11_SOURCE
+// _LARGEFILE_SOURCE		Large File Support
+//		<http://ftp.sas.com/standards/large.file/x_open.20Mar96.html>

+// ANSI macros:

+// POSIX macros:
+// _POSIX_SOURCE == 1		IEEE Std 1003.1 (version?)

+// of rename() that's used is the POSIX one).  If none of the "major"
+// feature-test macros is defined, _NETBSD_SOURCE is assumed.

+// There are also "minor" feature-test macros, which enable extra

+//
+// ANSI macros:

+//
+// POSIX macros:
+// _POSIX_SOURCE == 1		IEEE Std 1003.1 (version?)
+// _POSIX_C_SOURCE == 1		IEEE Std 1003.1-1990
+// _POSIX_C_SOURCE == 2		IEEE Std 1003.2-1992

+// _POSIX_C_SOURCE == 200809L   IEEE Std 1003.1-2008
+//
+// X/Open macros:
+// _XOPEN_SOURCE		System Interfaces and Headers, Issue 4, Ver 2
+// _XOPEN_SOURCE_EXTENDED == 1	XSH4.2 UNIX extensions
+// _XOPEN_SOURCE == 500		System Interfaces and Headers, Issue 5

+//
+// If more than one of these "major" feature-test macros is defined,

+// conflict, the earlier standard in the above list has precedence (so
+// if both _POSIX_C_SOURCE and _NETBSD_SOURCE are defined, the version
+// of rename() that's used is the POSIX one).  If none of the "major"
+// feature-test macros is defined, _NETBSD_SOURCE is assumed.
+//
+// There are also "minor" feature-test macros, which enable extra
+// functionality in addition to some base standard.  They should be
+// defined along with one of the "major" macros.  The "minor" macros

+
+// Feature-test macros are defined by several standards, and allow an
+// application to specify what symbols they want the system headers to
+// expose, and hence what standard they want them to conform to.
+// There are two classes of feature-test macros.  The first class
+// specify complete standards, and if one of these is defined, header
+// files will try to conform to the relevant standard.  They are:
+//
+// ANSI macros:
+// _ANSI_SOURCE			ANSI C89
+//
+// POSIX macros:
+// _POSIX_SOURCE == 1		IEEE Std 1003.1 (version?)
+// _POSIX_C_SOURCE == 1		IEEE Std 1003.1-1990
+// _POSIX_C_SOURCE == 2		IEEE Std 1003.2-1992

+// _POSIX_C_SOURCE == 200809L   IEEE Std 1003.1-2008
+//
+// X/Open macros:
+// _XOPEN_SOURCE		System Interfaces and Headers, Issue 4, Ver 2
+// _XOPEN_SOURCE_EXTENDED == 1	XSH4.2 UNIX extensions
+// _XOPEN_SOURCE == 500		System Interfaces and Headers, Issue 5
+// _XOPEN_SOURCE == 520		Networking Services (XNS), Issue 5.2
+// _XOPEN_SOURCE == 600		IEEE Std 1003.1-2001, XSI option
+// _XOPEN_SOURCE == 700		IEEE Std 1003.1-2008, XSI option
+//
+// NetBSD macros:
+// _NETBSD_SOURCE == 1		Make all NetBSD features available.
+//
+// If more than one of these "major" feature-test macros is defined,

-// Common definition of pthread_mutex_t.
+// Arch-specific definitions.  Each architecture must define the following
+//    macros to define the expected sizes of pthread data types:
+//
+//    __SIZEOF_PTHREAD_ATTR_T        - size of pthread_attr_t.
+//    __SIZEOF_PTHREAD_MUTEX_T       - size of pthread_mutex_t.
+//    __SIZEOF_PTHREAD_MUTEXATTR_T   - size of pthread_mutexattr_t.
+//    __SIZEOF_PTHREAD_COND_T        - size of pthread_cond_t.
+//    __SIZEOF_PTHREAD_CONDATTR_T    - size of pthread_condattr_t.
+//    __SIZEOF_PTHREAD_RWLOCK_T      - size of pthread_rwlock_t.
+//    __SIZEOF_PTHREAD_RWLOCKATTR_T  - size of pthread_rwlockattr_t.
+//    __SIZEOF_PTHREAD_BARRIER_T     - size of pthread_barrier_t.
+//    __SIZEOF_PTHREAD_BARRIERATTR_T - size of pthread_barrierattr_t.
+//
+//    The additional macro defines any constraint for the lock alignment
+//    inside the thread structures:
+//
+//    __LOCK_ALIGNMENT - for internal lock/futex usage.
+//
+//    Same idea but for the once locking primitive:
+//
+//    __ONCE_ALIGNMENT - for pthread_once_t/once_flag definition.

+// Public domain.
+//
+// NOTE: Do not protect this header against multiple inclusion.  Doing
+// so can have subtle side-effects due to header file inclusion order
+// and testing of e.g. _POSIX_SOURCE vs. _POSIX_C_SOURCE.  Instead,
+// protect each CPP macro that we want to supply.
+
+// Feature-test macros are defined by several standards, and allow an
+// application to specify what symbols they want the system headers to
+// expose, and hence what standard they want them to conform to.
+// There are two classes of feature-test macros.  The first class
+// specify complete standards, and if one of these is defined, header
+// files will try to conform to the relevant standard.  They are:
+//
+// ANSI macros:
+// _ANSI_SOURCE			ANSI C89
+//
+// POSIX macros:
+// _POSIX_SOURCE == 1		IEEE Std 1003.1 (version?)
+// _POSIX_C_SOURCE == 1		IEEE Std 1003.1-1990
+// _POSIX_C_SOURCE == 2		IEEE Std 1003.2-1992
+// _POSIX_C_SOURCE == 199309L	IEEE Std 1003.1b-1993
+// _POSIX_C_SOURCE == 199506L	ISO/IEC 9945-1:1996
+// _POSIX_C_SOURCE == 200112L	IEEE Std 1003.1-2001
+// _POSIX_C_SOURCE == 200809L   IEEE Std 1003.1-2008
+//
+// X/Open macros:
+// _XOPEN_SOURCE		System Interfaces and Headers, Issue 4, Ver 2
+// _XOPEN_SOURCE_EXTENDED == 1	XSH4.2 UNIX extensions
+// _XOPEN_SOURCE == 500		System Interfaces and Headers, Issue 5
+// _XOPEN_SOURCE == 520		Networking Services (XNS), Issue 5.2
+// _XOPEN_SOURCE == 600		IEEE Std 1003.1-2001, XSI option
+// _XOPEN_SOURCE == 700		IEEE Std 1003.1-2008, XSI option
+//
+// NetBSD macros:
+// _NETBSD_SOURCE == 1		Make all NetBSD features available.
+//
+// If more than one of these "major" feature-test macros is defined,
+// then the set of facilities provided (and namespace used) is the
+// union of that specified by the relevant standards, and in case of
+// conflict, the earlier standard in the above list has precedence (so
+// if both _POSIX_C_SOURCE and _NETBSD_SOURCE are defined, the version
+// of rename() that's used is the POSIX one).  If none of the "major"
+// feature-test macros is defined, _NETBSD_SOURCE is assumed.
+//
+// There are also "minor" feature-test macros, which enable extra
+// functionality in addition to some base standard.  They should be
+// defined along with one of the "major" macros.  The "minor" macros
+// are:
+//
+// _REENTRANT
+// _ISOC99_SOURCE
+// _ISOC11_SOURCE
+// _LARGEFILE_SOURCE		Large File Support
+//		<http://ftp.sas.com/standards/large.file/x_open.20Mar96.html>

+// Public domain.
+//
+// NOTE: Do not protect this header against multiple inclusion.  Doing
+// so can have subtle side-effects due to header file inclusion order
+// and testing of e.g. _POSIX_SOURCE vs. _POSIX_C_SOURCE.  Instead,
+// protect each CPP macro that we want to supply.
+
+// Feature-test macros are defined by several standards, and allow an
+// application to specify what symbols they want the system headers to
+// expose, and hence what standard they want them to conform to.
+// There are two classes of feature-test macros.  The first class
+// specify complete standards, and if one of these is defined, header
+// files will try to conform to the relevant standard.  They are:
+//
+// ANSI macros:
+// _ANSI_SOURCE			ANSI C89
+//
+// POSIX macros:
+// _POSIX_SOURCE == 1		IEEE Std 1003.1 (version?)
+// _POSIX_C_SOURCE == 1		IEEE Std 1003.1-1990
+// _POSIX_C_SOURCE == 2		IEEE Std 1003.2-1992
+// _POSIX_C_SOURCE == 199309L	IEEE Std 1003.1b-1993
+// _POSIX_C_SOURCE == 199506L	ISO/IEC 9945-1:1996
+// _POSIX_C_SOURCE == 200112L	IEEE Std 1003.1-2001
+// _POSIX_C_SOURCE == 200809L   IEEE Std 1003.1-2008
+//
+// X/Open macros:
+// _XOPEN_SOURCE		System Interfaces and Headers, Issue 4, Ver 2
+// _XOPEN_SOURCE_EXTENDED == 1	XSH4.2 UNIX extensions
+// _XOPEN_SOURCE == 500		System Interfaces and Headers, Issue 5
+// _XOPEN_SOURCE == 520		Networking Services (XNS), Issue 5.2
+// _XOPEN_SOURCE == 600		IEEE Std 1003.1-2001, XSI option
+// _XOPEN_SOURCE == 700		IEEE Std 1003.1-2008, XSI option
+//
+// NetBSD macros:
+// _NETBSD_SOURCE == 1		Make all NetBSD features available.
+//
+// If more than one of these "major" feature-test macros is defined,
+// then the set of facilities provided (and namespace used) is the
+// union of that specified by the relevant standards, and in case of
+// conflict, the earlier standard in the above list has precedence (so
+// if both _POSIX_C_SOURCE and _NETBSD_SOURCE are defined, the version
+// of rename() that's used is the POSIX one).  If none of the "major"
+// feature-test macros is defined, _NETBSD_SOURCE is assumed.
+//
+// There are also "minor" feature-test macros, which enable extra
+// functionality in addition to some base standard.  They should be
+// defined along with one of the "major" macros.  The "minor" macros
+// are:
+//
+// _REENTRANT
+// _ISOC99_SOURCE
+// _ISOC11_SOURCE
+// _LARGEFILE_SOURCE		Large File Support
+//		<http://ftp.sas.com/standards/large.file/x_open.20Mar96.html>
+
+// Definitions for byte order, according to byte significance from low
+// address to high.
+
+// C-family endian-ness definitions

+// Public domain.
+//
+// NOTE: Do not protect this header against multiple inclusion.  Doing
+// so can have subtle side-effects due to header file inclusion order
+// and testing of e.g. _POSIX_SOURCE vs. _POSIX_C_SOURCE.  Instead,
+// protect each CPP macro that we want to supply.
+
+// Feature-test macros are defined by several standards, and allow an
+// application to specify what symbols they want the system headers to
+// expose, and hence what standard they want them to conform to.
+// There are two classes of feature-test macros.  The first class
+// specify complete standards, and if one of these is defined, header
+// files will try to conform to the relevant standard.  They are:
+//
+// ANSI macros:
+// _ANSI_SOURCE			ANSI C89
+//
+// POSIX macros:
+// _POSIX_SOURCE == 1		IEEE Std 1003.1 (version?)
+// _POSIX_C_SOURCE == 1		IEEE Std 1003.1-1990
+// _POSIX_C_SOURCE == 2		IEEE Std 1003.2-1992
+// _POSIX_C_SOURCE == 199309L	IEEE Std 1003.1b-1993
+// _POSIX_C_SOURCE == 199506L	ISO/IEC 9945-1:1996
+// _POSIX_C_SOURCE == 200112L	IEEE Std 1003.1-2001
+// _POSIX_C_SOURCE == 200809L   IEEE Std 1003.1-2008
+//
+// X/Open macros:
+// _XOPEN_SOURCE		System Interfaces and Headers, Issue 4, Ver 2
+// _XOPEN_SOURCE_EXTENDED == 1	XSH4.2 UNIX extensions
+// _XOPEN_SOURCE == 500		System Interfaces and Headers, Issue 5
+// _XOPEN_SOURCE == 520		Networking Services (XNS), Issue 5.2
+// _XOPEN_SOURCE == 600		IEEE Std 1003.1-2001, XSI option
+// _XOPEN_SOURCE == 700		IEEE Std 1003.1-2008, XSI option
+//
+// NetBSD macros:
+// _NETBSD_SOURCE == 1		Make all NetBSD features available.
+//
+// If more than one of these "major" feature-test macros is defined,
+// then the set of facilities provided (and namespace used) is the
+// union of that specified by the relevant standards, and in case of
+// conflict, the earlier standard in the above list has precedence (so
+// if both _POSIX_C_SOURCE and _NETBSD_SOURCE are defined, the version
+// of rename() that's used is the POSIX one).  If none of the "major"
+// feature-test macros is defined, _NETBSD_SOURCE is assumed.
+//
+// There are also "minor" feature-test macros, which enable extra
+// functionality in addition to some base standard.  They should be
+// defined along with one of the "major" macros.  The "minor" macros
+// are:
+//
+// _REENTRANT
+// _ISOC99_SOURCE
+// _ISOC11_SOURCE
+// _LARGEFILE_SOURCE		Large File Support
+//		<http://ftp.sas.com/standards/large.file/x_open.20Mar96.html>

+// Public domain.
+//
+// NOTE: Do not protect this header against multiple inclusion.  Doing
+// so can have subtle side-effects due to header file inclusion order
+// and testing of e.g. _POSIX_SOURCE vs. _POSIX_C_SOURCE.  Instead,
+// protect each CPP macro that we want to supply.
+
+// Feature-test macros are defined by several standards, and allow an
+// application to specify what symbols they want the system headers to
+// expose, and hence what standard they want them to conform to.
+// There are two classes of feature-test macros.  The first class
+// specify complete standards, and if one of these is defined, header
+// files will try to conform to the relevant standard.  They are:
+//
+// ANSI macros:
+// _ANSI_SOURCE			ANSI C89
+//
+// POSIX macros:
+// _POSIX_SOURCE == 1		IEEE Std 1003.1 (version?)
+// _POSIX_C_SOURCE == 1		IEEE Std 1003.1-1990
+// _POSIX_C_SOURCE == 2		IEEE Std 1003.2-1992
+// _POSIX_C_SOURCE == 199309L	IEEE Std 1003.1b-1993
+// _POSIX_C_SOURCE == 199506L	ISO/IEC 9945-1:1996
+// _POSIX_C_SOURCE == 200112L	IEEE Std 1003.1-2001
+// _POSIX_C_SOURCE == 200809L   IEEE Std 1003.1-2008
+//
+// X/Open macros:
+// _XOPEN_SOURCE		System Interfaces and Headers, Issue 4, Ver 2
+// _XOPEN_SOURCE_EXTENDED == 1	XSH4.2 UNIX extensions
+// _XOPEN_SOURCE == 500		System Interfaces and Headers, Issue 5
+// _XOPEN_SOURCE == 520		Networking Services (XNS), Issue 5.2
+// _XOPEN_SOURCE == 600		IEEE Std 1003.1-2001, XSI option
+// _XOPEN_SOURCE == 700		IEEE Std 1003.1-2008, XSI option
+//
+// NetBSD macros:
+// _NETBSD_SOURCE == 1		Make all NetBSD features available.
+//
+// If more than one of these "major" feature-test macros is defined,
+// then the set of facilities provided (and namespace used) is the
+// union of that specified by the relevant standards, and in case of
+// conflict, the earlier standard in the above list has precedence (so
+// if both _POSIX_C_SOURCE and _NETBSD_SOURCE are defined, the version
+// of rename() that's used is the POSIX one).  If none of the "major"
+// feature-test macros is defined, _NETBSD_SOURCE is assumed.
+//
+// There are also "minor" feature-test macros, which enable extra
+// functionality in addition to some base standard.  They should be
+// defined along with one of the "major" macros.  The "minor" macros
+// are:
+//
+// _REENTRANT
+// _ISOC99_SOURCE
+// _ISOC11_SOURCE
+// _LARGEFILE_SOURCE		Large File Support
+//		<http://ftp.sas.com/standards/large.file/x_open.20Mar96.html>

+//
+// NOTE: Do not protect this header against multiple inclusion.  Doing
+// so can have subtle side-effects due to header file inclusion order
+// and testing of e.g. _POSIX_SOURCE vs. _POSIX_C_SOURCE.  Instead,
+// protect each CPP macro that we want to supply.
+
+// Feature-test macros are defined by several standards, and allow an
+// application to specify what symbols they want the system headers to
+// expose, and hence what standard they want them to conform to.
+// There are two classes of feature-test macros.  The first class
+// specify complete standards, and if one of these is defined, header
+// files will try to conform to the relevant standard.  They are:
+//
+// ANSI macros:
+// _ANSI_SOURCE			ANSI C89
+//
+// POSIX macros:
+// _POSIX_SOURCE == 1		IEEE Std 1003.1 (version?)
+// _POSIX_C_SOURCE == 1		IEEE Std 1003.1-1990
+// _POSIX_C_SOURCE == 2		IEEE Std 1003.2-1992
+// _POSIX_C_SOURCE == 199309L	IEEE Std 1003.1b-1993
+// _POSIX_C_SOURCE == 199506L	ISO/IEC 9945-1:1996
+// _POSIX_C_SOURCE == 200112L	IEEE Std 1003.1-2001
+// _POSIX_C_SOURCE == 200809L   IEEE Std 1003.1-2008
+//
+// X/Open macros:
+// _XOPEN_SOURCE		System Interfaces and Headers, Issue 4, Ver 2
+// _XOPEN_SOURCE_EXTENDED == 1	XSH4.2 UNIX extensions
+// _XOPEN_SOURCE == 500		System Interfaces and Headers, Issue 5
+// _XOPEN_SOURCE == 520		Networking Services (XNS), Issue 5.2
+// _XOPEN_SOURCE == 600		IEEE Std 1003.1-2001, XSI option
+// _XOPEN_SOURCE == 700		IEEE Std 1003.1-2008, XSI option
+//
+// NetBSD macros:
+// _NETBSD_SOURCE == 1		Make all NetBSD features available.
+//
+// If more than one of these "major" feature-test macros is defined,
+// then the set of facilities provided (and namespace used) is the
+// union of that specified by the relevant standards, and in case of
+// conflict, the earlier standard in the above list has precedence (so
+// if both _POSIX_C_SOURCE and _NETBSD_SOURCE are defined, the version
+// of rename() that's used is the POSIX one).  If none of the "major"
+// feature-test macros is defined, _NETBSD_SOURCE is assumed.
+//
+// There are also "minor" feature-test macros, which enable extra
+// functionality in addition to some base standard.  They should be
+// defined along with one of the "major" macros.  The "minor" macros
+// are:
+//
+// _REENTRANT
+// _ISOC99_SOURCE
+// _ISOC11_SOURCE
+// _LARGEFILE_SOURCE		Large File Support
+//		<http://ftp.sas.com/standards/large.file/x_open.20Mar96.html>

+// Public domain.
+//
+// NOTE: Do not protect this header against multiple inclusion.  Doing
+// so can have subtle side-effects due to header file inclusion order
+// and testing of e.g. _POSIX_SOURCE vs. _POSIX_C_SOURCE.  Instead,
+// protect each CPP macro that we want to supply.
+
+// Feature-test macros are defined by several standards, and allow an
+// application to specify what symbols they want the system headers to
+// expose, and hence what standard they want them to conform to.
+// There are two classes of feature-test macros.  The first class
+// specify complete standards, and if one of these is defined, header
+// files will try to conform to the relevant standard.  They are:
+//
+// ANSI macros:
+// _ANSI_SOURCE			ANSI C89
+//
+// POSIX macros:
+// _POSIX_SOURCE == 1		IEEE Std 1003.1 (version?)
+// _POSIX_C_SOURCE == 1		IEEE Std 1003.1-1990
+// _POSIX_C_SOURCE == 2		IEEE Std 1003.2-1992
+// _POSIX_C_SOURCE == 199309L	IEEE Std 1003.1b-1993
+// _POSIX_C_SOURCE == 199506L	ISO/IEC 9945-1:1996
+// _POSIX_C_SOURCE == 200112L	IEEE Std 1003.1-2001
+// _POSIX_C_SOURCE == 200809L   IEEE Std 1003.1-2008
+//
+// X/Open macros:
+// _XOPEN_SOURCE		System Interfaces and Headers, Issue 4, Ver 2
+// _XOPEN_SOURCE_EXTENDED == 1	XSH4.2 UNIX extensions
+// _XOPEN_SOURCE == 500		System Interfaces and Headers, Issue 5
+// _XOPEN_SOURCE == 520		Networking Services (XNS), Issue 5.2
+// _XOPEN_SOURCE == 600		IEEE Std 1003.1-2001, XSI option
+// _XOPEN_SOURCE == 700		IEEE Std 1003.1-2008, XSI option
+//
+// NetBSD macros:
+// _NETBSD_SOURCE == 1		Make all NetBSD features available.
+//
+// If more than one of these "major" feature-test macros is defined,
+// then the set of facilities provided (and namespace used) is the
+// union of that specified by the relevant standards, and in case of
+// conflict, the earlier standard in the above list has precedence (so
+// if both _POSIX_C_SOURCE and _NETBSD_SOURCE are defined, the version
+// of rename() that's used is the POSIX one).  If none of the "major"
+// feature-test macros is defined, _NETBSD_SOURCE is assumed.
+//
+// There are also "minor" feature-test macros, which enable extra
+// functionality in addition to some base standard.  They should be
+// defined along with one of the "major" macros.  The "minor" macros
+// are:
+//
+// _REENTRANT
+// _ISOC99_SOURCE
+// _ISOC11_SOURCE
+// _LARGEFILE_SOURCE		Large File Support
+//		<http://ftp.sas.com/standards/large.file/x_open.20Mar96.html>
+
+// Definitions for byte order, according to byte significance from low
+// address to high.
+
+// C-family endian-ness definitions

+// Written by Klaus Klein <kleink@NetBSD.org>, February 2, 1998.
+// Public domain.
+//
+// NOTE: Do not protect this header against multiple inclusion.  Doing
+// so can have subtle side-effects due to header file inclusion order
+// and testing of e.g. _POSIX_SOURCE vs. _POSIX_C_SOURCE.  Instead,
+// protect each CPP macro that we want to supply.
+
+// Feature-test macros are defined by several standards, and allow an
+// application to specify what symbols they want the system headers to
+// expose, and hence what standard they want them to conform to.
+// There are two classes of feature-test macros.  The first class
+// specify complete standards, and if one of these is defined, header
+// files will try to conform to the relevant standard.  They are:
+//
+// ANSI macros:
+// _ANSI_SOURCE			ANSI C89
+//
+// POSIX macros:
+// _POSIX_SOURCE == 1		IEEE Std 1003.1 (version?)
+// _POSIX_C_SOURCE == 1		IEEE Std 1003.1-1990
+// _POSIX_C_SOURCE == 2		IEEE Std 1003.2-1992
+// _POSIX_C_SOURCE == 199309L	IEEE Std 1003.1b-1993
+// _POSIX_C_SOURCE == 199506L	ISO/IEC 9945-1:1996
+// _POSIX_C_SOURCE == 200112L	IEEE Std 1003.1-2001
+// _POSIX_C_SOURCE == 200809L   IEEE Std 1003.1-2008
+//
+// X/Open macros:
+// _XOPEN_SOURCE		System Interfaces and Headers, Issue 4, Ver 2
+// _XOPEN_SOURCE_EXTENDED == 1	XSH4.2 UNIX extensions
+// _XOPEN_SOURCE == 500		System Interfaces and Headers, Issue 5
+// _XOPEN_SOURCE == 520		Networking Services (XNS), Issue 5.2
+// _XOPEN_SOURCE == 600		IEEE Std 1003.1-2001, XSI option
+// _XOPEN_SOURCE == 700		IEEE Std 1003.1-2008, XSI option
+//
+// NetBSD macros:
+// _NETBSD_SOURCE == 1		Make all NetBSD features available.
+//
+// If more than one of these "major" feature-test macros is defined,
+// then the set of facilities provided (and namespace used) is the
+// union of that specified by the relevant standards, and in case of
+// conflict, the earlier standard in the above list has precedence (so
+// if both _POSIX_C_SOURCE and _NETBSD_SOURCE are defined, the version
+// of rename() that's used is the POSIX one).  If none of the "major"
+// feature-test macros is defined, _NETBSD_SOURCE is assumed.
+//
+// There are also "minor" feature-test macros, which enable extra
+// functionality in addition to some base standard.  They should be
+// defined along with one of the "major" macros.  The "minor" macros
+// are:
+//
+// _REENTRANT
+// _ISOC99_SOURCE
+// _ISOC11_SOURCE
+// _LARGEFILE_SOURCE		Large File Support
+//		<http://ftp.sas.com/standards/large.file/x_open.20Mar96.html>

+// Public domain.
+//
+// NOTE: Do not protect this header against multiple inclusion.  Doing
+// so can have subtle side-effects due to header file inclusion order
+// and testing of e.g. _POSIX_SOURCE vs. _POSIX_C_SOURCE.  Instead,
+// protect each CPP macro that we want to supply.
+
+// Feature-test macros are defined by several standards, and allow an
+// application to specify what symbols they want the system headers to
+// expose, and hence what standard they want them to conform to.
+// There are two classes of feature-test macros.  The first class
+// specify complete standards, and if one of these is defined, header
+// files will try to conform to the relevant standard.  They are:
+//
+// ANSI macros:
+// _ANSI_SOURCE			ANSI C89
+//
+// POSIX macros:
+// _POSIX_SOURCE == 1		IEEE Std 1003.1 (version?)
+// _POSIX_C_SOURCE == 1		IEEE Std 1003.1-1990
+// _POSIX_C_SOURCE == 2		IEEE Std 1003.2-1992
+// _POSIX_C_SOURCE == 199309L	IEEE Std 1003.1b-1993
+// _POSIX_C_SOURCE == 199506L	ISO/IEC 9945-1:1996
+// _POSIX_C_SOURCE == 200112L	IEEE Std 1003.1-2001
+// _POSIX_C_SOURCE == 200809L   IEEE Std 1003.1-2008
+//
+// X/Open macros:
+// _XOPEN_SOURCE		System Interfaces and Headers, Issue 4, Ver 2
+// _XOPEN_SOURCE_EXTENDED == 1	XSH4.2 UNIX extensions
+// _XOPEN_SOURCE == 500		System Interfaces and Headers, Issue 5
+// _XOPEN_SOURCE == 520		Networking Services (XNS), Issue 5.2
+// _XOPEN_SOURCE == 600		IEEE Std 1003.1-2001, XSI option
+// _XOPEN_SOURCE == 700		IEEE Std 1003.1-2008, XSI option
+//
+// NetBSD macros:
+// _NETBSD_SOURCE == 1		Make all NetBSD features available.
+//
+// If more than one of these "major" feature-test macros is defined,
+// then the set of facilities provided (and namespace used) is the
+// union of that specified by the relevant standards, and in case of
+// conflict, the earlier standard in the above list has precedence (so
+// if both _POSIX_C_SOURCE and _NETBSD_SOURCE are defined, the version
+// of rename() that's used is the POSIX one).  If none of the "major"
+// feature-test macros is defined, _NETBSD_SOURCE is assumed.
+//
+// There are also "minor" feature-test macros, which enable extra
+// functionality in addition to some base standard.  They should be
+// defined along with one of the "major" macros.  The "minor" macros
+// are:
+//
+// _REENTRANT
+// _ISOC99_SOURCE
+// _ISOC11_SOURCE
+// _LARGEFILE_SOURCE		Large File Support
+//		<http://ftp.sas.com/standards/large.file/x_open.20Mar96.html>
+
+// Definitions for byte order, according to byte significance from low
+// address to high.

+//
+// NOTE: Do not protect this header against multiple inclusion.  Doing
+// so can have subtle side-effects due to header file inclusion order
+// and testing of e.g. _POSIX_SOURCE vs. _POSIX_C_SOURCE.  Instead,
+// protect each CPP macro that we want to supply.
+
+// Feature-test macros are defined by several standards, and allow an
+// application to specify what symbols they want the system headers to
+// expose, and hence what standard they want them to conform to.
+// There are two classes of feature-test macros.  The first class
+// specify complete standards, and if one of these is defined, header
+// files will try to conform to the relevant standard.  They are:
+//
+// ANSI macros:
+// _ANSI_SOURCE			ANSI C89
+//
+// POSIX macros:
+// _POSIX_SOURCE == 1		IEEE Std 1003.1 (version?)
+// _POSIX_C_SOURCE == 1		IEEE Std 1003.1-1990
+// _POSIX_C_SOURCE == 2		IEEE Std 1003.2-1992
+// _POSIX_C_SOURCE == 199309L	IEEE Std 1003.1b-1993
+// _POSIX_C_SOURCE == 199506L	ISO/IEC 9945-1:1996
+// _POSIX_C_SOURCE == 200112L	IEEE Std 1003.1-2001
+// _POSIX_C_SOURCE == 200809L   IEEE Std 1003.1-2008
+//
+// X/Open macros:
+// _XOPEN_SOURCE		System Interfaces and Headers, Issue 4, Ver 2
+// _XOPEN_SOURCE_EXTENDED == 1	XSH4.2 UNIX extensions
+// _XOPEN_SOURCE == 500		System Interfaces and Headers, Issue 5
+// _XOPEN_SOURCE == 520		Networking Services (XNS), Issue 5.2
+// _XOPEN_SOURCE == 600		IEEE Std 1003.1-2001, XSI option
+// _XOPEN_SOURCE == 700		IEEE Std 1003.1-2008, XSI option
+//
+// NetBSD macros:
+// _NETBSD_SOURCE == 1		Make all NetBSD features available.
+//
+// If more than one of these "major" feature-test macros is defined,
+// then the set of facilities provided (and namespace used) is the
+// union of that specified by the relevant standards, and in case of
+// conflict, the earlier standard in the above list has precedence (so
+// if both _POSIX_C_SOURCE and _NETBSD_SOURCE are defined, the version
+// of rename() that's used is the POSIX one).  If none of the "major"
+// feature-test macros is defined, _NETBSD_SOURCE is assumed.
+//
+// There are also "minor" feature-test macros, which enable extra
+// functionality in addition to some base standard.  They should be
+// defined along with one of the "major" macros.  The "minor" macros
+// are:
+//
+// _REENTRANT
+// _ISOC99_SOURCE
+// _ISOC11_SOURCE
+// _LARGEFILE_SOURCE		Large File Support
+//		<http://ftp.sas.com/standards/large.file/x_open.20Mar96.html>

+// Feature-test macros are defined by several standards, and allow an
+// application to specify what symbols they want the system headers to
+// expose, and hence what standard they want them to conform to.
+// There are two classes of feature-test macros.  The first class
+// specify complete standards, and if one of these is defined, header
+// files will try to conform to the relevant standard.  They are:
+//
+// ANSI macros:
+// _ANSI_SOURCE			ANSI C89
+//
+// POSIX macros:
+// _POSIX_SOURCE == 1		IEEE Std 1003.1 (version?)
+// _POSIX_C_SOURCE == 1		IEEE Std 1003.1-1990
+// _POSIX_C_SOURCE == 2		IEEE Std 1003.2-1992

+// Public domain.
+//
+// NOTE: Do not protect this header against multiple inclusion.  Doing
+// so can have subtle side-effects due to header file inclusion order
+// and testing of e.g. _POSIX_SOURCE vs. _POSIX_C_SOURCE.  Instead,
+// protect each CPP macro that we want to supply.
+
+// Feature-test macros are defined by several standards, and allow an
+// application to specify what symbols they want the system headers to
+// expose, and hence what standard they want them to conform to.
+// There are two classes of feature-test macros.  The first class
+// specify complete standards, and if one of these is defined, header
+// files will try to conform to the relevant standard.  They are:
+//
+// ANSI macros:
+// _ANSI_SOURCE			ANSI C89
+//
+// POSIX macros:
+// _POSIX_SOURCE == 1		IEEE Std 1003.1 (version?)
+// _POSIX_C_SOURCE == 1		IEEE Std 1003.1-1990
+// _POSIX_C_SOURCE == 2		IEEE Std 1003.2-1992
+// _POSIX_C_SOURCE == 199309L	IEEE Std 1003.1b-1993
+// _POSIX_C_SOURCE == 199506L	ISO/IEC 9945-1:1996
+// _POSIX_C_SOURCE == 200112L	IEEE Std 1003.1-2001
+// _POSIX_C_SOURCE == 200809L   IEEE Std 1003.1-2008
+//
+// X/Open macros:
+// _XOPEN_SOURCE		System Interfaces and Headers, Issue 4, Ver 2
+// _XOPEN_SOURCE_EXTENDED == 1	XSH4.2 UNIX extensions
+// _XOPEN_SOURCE == 500		System Interfaces and Headers, Issue 5
+// _XOPEN_SOURCE == 520		Networking Services (XNS), Issue 5.2
+// _XOPEN_SOURCE == 600		IEEE Std 1003.1-2001, XSI option
+// _XOPEN_SOURCE == 700		IEEE Std 1003.1-2008, XSI option
+//
+// NetBSD macros:
+// _NETBSD_SOURCE == 1		Make all NetBSD features available.
+//
+// If more than one of these "major" feature-test macros is defined,
+// then the set of facilities provided (and namespace used) is the
+// union of that specified by the relevant standards, and in case of
+// conflict, the earlier standard in the above list has precedence (so
+// if both _POSIX_C_SOURCE and _NETBSD_SOURCE are defined, the version
+// of rename() that's used is the POSIX one).  If none of the "major"
+// feature-test macros is defined, _NETBSD_SOURCE is assumed.
+//
+// There are also "minor" feature-test macros, which enable extra
+// functionality in addition to some base standard.  They should be
+// defined along with one of the "major" macros.  The "minor" macros
+// are:
+//
+// _REENTRANT
+// _ISOC99_SOURCE
+// _ISOC11_SOURCE
+// _LARGEFILE_SOURCE		Large File Support
+//		<http://ftp.sas.com/standards/large.file/x_open.20Mar96.html>

+// This macro holds an monotonic increasing value, which indicates
+//    a specific fix/patch is present on trunk.  This value isn't related to
+//    minor/major version-macros.  It is increased on demand, if a big
+//    fix was applied to trunk.  This macro gets just increased on trunk.  For
+//    other branches its value won't be modified.
+
+// mingw.org's version macros: these make gcc to define
+//    MINGW32_SUPPORTS_MT_EH and to use the _CRT_MT global
+//    and the __mingwthr_key_dtor() function from the MinGW
+//    CRT in its private gthr-win32.h header.
+
+// Set VC specific compiler target macros.
+
+// For x86 we have always to prefix by underscore.
+
+// Special case nameless struct/union.
+
+// MinGW-w64 has some additional C99 printf/scanf feature support.
+//    So we add some helper macros to ease recognition of them.
+
+// If _FORTIFY_SOURCE is enabled, some inline functions may use
+//    __builtin_va_arg_pack().  GCC may report an error if the address
+//    of such a function is used.  Set _FORTIFY_VA_ARG=0 in this case.

+//     These macros are for use in OS header files. They enable function prototypes
+//     and Objective-C methods to be tagged with the OS version in which they
+//     were first available; and, if applicable, the OS version in which they
+//     became deprecated.
+//
+//     The desktop Mac OS X and iOS each have different version numbers.
+//     The __OSX_AVAILABLE_STARTING() macro allows you to specify both the desktop
+//     and iOS version numbers.  For instance:
+//         __OSX_AVAILABLE_STARTING(__MAC_10_2,__IPHONE_2_0)
+//     means the function/method was first available on Mac OS X 10.2 on the desktop
+//     and first available in iOS 2.0 on the iPhone.
+//
+//     If a function is available on one platform, but not the other a _NA (not
+//     applicable) parameter is used.  For instance:
+//             __OSX_AVAILABLE_STARTING(__MAC_10_3,__IPHONE_NA)
+//     means that the function/method was first available on Mac OS X 10.3, and it
+//     currently not implemented on the iPhone.
+//
+//     At some point, a function/method may be deprecated.  That means Apple
+//     recommends applications stop using the function, either because there is a
+//     better replacement or the functionality is being phased out.  Deprecated
+//     functions/methods can be tagged with a __OSX_AVAILABLE_BUT_DEPRECATED()
+//     macro which specifies the OS version where the function became available
+//     as well as the OS version in which it became deprecated.  For instance:
+//         __OSX_AVAILABLE_BUT_DEPRECATED(__MAC_10_0,__MAC_10_5,__IPHONE_NA,__IPHONE_NA)
+//     means that the function/method was introduced in Mac OS X 10.0, then
+//     became deprecated beginning in Mac OS X 10.5.  On iOS the function
+//     has never been available.
+//
+//     For these macros to function properly, a program must specify the OS version range
+//     it is targeting.  The min OS version is specified as an option to the compiler:
+//     -mmacosx-version-min=10.x when building for Mac OS X, and -miphoneos-version-min=y.z
+//     when building for the iPhone.  The upper bound for the OS version is rarely needed,
+//     but it can be set on the command line via: -D__MAC_OS_X_VERSION_MAX_ALLOWED=10x0 for
+//     Mac OS X and __IPHONE_OS_VERSION_MAX_ALLOWED = y0z00 for iOS.
+//
+//     Examples:
+//
+//         A function available in Mac OS X 10.5 and later, but not on the phone:
+//
+//             extern void mymacfunc() __OSX_AVAILABLE_STARTING(__MAC_10_5,__IPHONE_NA);
+//
+//
+//         An Objective-C method in Mac OS X 10.5 and later, but not on the phone:
+//
+//             @interface MyClass : NSObject
+//             -(void) mymacmethod __OSX_AVAILABLE_STARTING(__MAC_10_5,__IPHONE_NA);
+//             @end
+//
+//
+//         An enum available on the phone, but not available on Mac OS X:
+//
+//             #if __IPHONE_OS_VERSION_MIN_REQUIRED
+//                 enum { myEnum = 1 };
+//             #endif
+//            Note: this works when targeting the Mac OS X platform because
+//            __IPHONE_OS_VERSION_MIN_REQUIRED is undefined which evaluates to zero.
+//
+//
+//         An enum with values added in different iPhoneOS versions:
+//
+// 			enum {
+// 			    myX  = 1,	// Usable on iPhoneOS 2.1 and later
+// 			    myY  = 2,	// Usable on iPhoneOS 3.0 and later
+// 			    myZ  = 3,	// Usable on iPhoneOS 3.0 and later
+// 				...
+// 		      Note: you do not want to use #if with enumeration values
+// 			  when a client needs to see all values at compile time
+// 			  and use runtime logic to only use the viable values.
+//
+//
+//     It is also possible to use the *_VERSION_MIN_REQUIRED in source code to make one
+//     source base that can be compiled to target a range of OS versions.  It is best
+//     to not use the _MAC_* and __IPHONE_* macros for comparisons, but rather their values.
+//     That is because you might get compiled on an old OS that does not define a later
+//     OS version macro, and in the C preprocessor undefined values evaluate to zero
+//     in expresssions, which could cause the #if expression to evaluate in an unexpected
+//     way.
+//
+//         #ifdef __MAC_OS_X_VERSION_MIN_REQUIRED
+//             // code only compiled when targeting Mac OS X and not iPhone
+//             // note use of 1050 instead of __MAC_10_5
+//             #if __MAC_OS_X_VERSION_MIN_REQUIRED < 1050
+//                 // code in here might run on pre-Leopard OS
+//             #else
+//                 // code here can assume Leopard or later
+//             #endif
+//         #endif
+//
+//
+
+// __API_TO_BE_DEPRECATED is used as a version number in API that will be deprecated
+// in an upcoming release. This soft deprecation is an intermediate step before formal
+// deprecation to notify developers about the API before compiler warnings are generated.
+// You can find all places in your code that use soft deprecated API by redefining the
+// value of this macro to your current minimum deployment target, for example:
+// (macOS)
+//   clang -D__API_TO_BE_DEPRECATED=10.12 <other compiler flags>
+// (iOS)
+//   clang -D__API_TO_BE_DEPRECATED=11.0 <other compiler flags>
+
+// __MAC_NA is not defined to a value but is uses as a token by macros to indicate that the API is unavailable
+
+// __IPHONE_NA is not defined to a value but is uses as a token by macros to indicate that the API is unavailable
+
+//  DO NOT EDIT THIS FILE.

+
+// This SDK is designed to work with clang and specific versions of
+// gcc >= 4.0 with Apple's patch sets
+
+// Compatibility with compilers and environments that don't support compiler
+// feature checking function-like macros.
+
+// The __CONCAT macro is used to concatenate parts of symbol names, e.g.
+// with "#define OLD(foo) __CONCAT(old,foo)", OLD(foo) produces oldfoo.
+// The __CONCAT macro is a bit tricky -- make sure you don't put spaces
+// in between its arguments.  __CONCAT can also concatenate double-quoted
+// strings produced by the __STRING macro, but this only works with ANSI C.
+
+// __unused denotes variables and functions that may not be used, preventing
+// the compiler from warning about it if not used.
+
+// __used forces variables and functions to be included even if it appears
+// to the compiler that they are not used (and would thust be discarded).
+
+// __cold marks code used for debugging or that is rarely taken
+// and tells the compiler to optimize for size and outline code.
+
+// __deprecated causes the compiler to produce a warning when encountering
+// code using the deprecated functionality.
+// __deprecated_msg() does the same, and compilers that support it will print
+// a message along with the deprecation warning.
+// This may require turning on such warning with the -Wdeprecated flag.
+// __deprecated_enum_msg() should be used on enums, and compilers that support
+// it will print the deprecation warning.
+// __kpi_deprecated() specifically indicates deprecation of kernel programming
+// interfaces in Kernel.framework used by KEXTs.
+
+// __unavailable causes the compiler to error out when encountering
+// code using the tagged function of variable.
+
+// Delete pseudo-keywords wherever they are not available or needed.
+
+// We use `__restrict' as a way to define the `restrict' type qualifier
+// without disturbing older software that is unaware of C99 keywords.
+
+// Compatibility with compilers and environments that don't support the
+// nullability feature.
+
+// __disable_tail_calls causes the compiler to not perform tail call
+// optimization inside the marked function.
+
+// __not_tail_called causes the compiler to prevent tail call optimization
+// on statically bound calls to the function.  It has no effect on indirect
+// calls.  Virtual functions, objective-c methods, and functions marked as
+// "always_inline" cannot be marked as __not_tail_called.
+
+// __result_use_check warns callers of a function that not using the function
+// return value is a bug, i.e. dismissing malloc() return value results in a
+// memory leak.
+
+// __swift_unavailable causes the compiler to mark a symbol as specifically
+// unavailable in Swift, regardless of any other availability in C.
+
+// __abortlike is the attribute to put on functions like abort() that are
+// typically used to mark assertions. These optimize the codegen
+// for outlining while still maintaining debugability.
+
+// Declaring inline functions within headers is error-prone due to differences
+// across various versions of the C language and extensions.  __header_inline
+// can be used to declare inline functions within system headers.  In cases
+// where you want to force inlining instead of letting the compiler make
+// the decision, you can use __header_always_inline.
+//
+// Be aware that using inline for functions which compilers may also provide
+// builtins can behave differently under various compilers.  If you intend to
+// provide an inline version of such a function, you may want to use a macro
+// instead.
+//
+// The check for !__GNUC__ || __clang__ is because gcc doesn't correctly
+// support c99 inline in some cases:
+// http://gcc.gnu.org/bugzilla/show_bug.cgi?id=55965
+
+// Compiler-dependent macros that bracket portions of code where the
+// "-Wunreachable-code" warning should be ignored. Please use sparingly.
+
+// Compiler-dependent macros to declare that functions take printf-like
+// or scanf-like arguments.  They are null except for versions of gcc
+// that are known to support the features properly.  Functions declared
+// with these attributes will cause compilation warnings if there is a
+// mismatch between the format string and subsequent function parameter
+// types.
+
+// Source compatibility only, ID string not emitted in object file
+
+// __alloc_size can be used to label function arguments that represent the
+// size of memory that the function allocates and returns. The one-argument
+// form labels a single argument that gives the allocation size (where the
+// arguments are numbered from 1):
+//
+// void	*malloc(size_t __size) __alloc_size(1);
+//
+// The two-argument form handles the case where the size is calculated as the
+// product of two arguments:
+//
+// void	*calloc(size_t __count, size_t __size) __alloc_size(1,2);
+
+// COMPILATION ENVIRONMENTS -- see compat(5) for additional detail
+//
+// DEFAULT	By default newly complied code will get POSIX APIs plus
+//		Apple API extensions in scope.
+//
+//		Most users will use this compilation environment to avoid
+//		behavioral differences between 32 and 64 bit code.
+//
+// LEGACY	Defining _NONSTD_SOURCE will get pre-POSIX APIs plus Apple
+//		API extensions in scope.
+//
+//		This is generally equivalent to the Tiger release compilation
+//		environment, except that it cannot be applied to 64 bit code;
+//		its use is discouraged.
+//
+//		We expect this environment to be deprecated in the future.
+//
+// STRICT	Defining _POSIX_C_SOURCE or _XOPEN_SOURCE restricts the
+//		available APIs to exactly the set of APIs defined by the
+//		corresponding standard, based on the value defined.
+//
+//		A correct, portable definition for _POSIX_C_SOURCE is 200112L.
+//		A correct, portable definition for _XOPEN_SOURCE is 600L.
+//
+//		Apple API extensions are not visible in this environment,
+//		which can cause Apple specific code to fail to compile,
+//		or behave incorrectly if prototypes are not in scope or
+//		warnings about missing prototypes are not enabled or ignored.
+//
+// In any compilation environment, for correct symbol resolution to occur,
+// function prototypes must be in scope.  It is recommended that all Apple
+// tools users add either the "-Wall" or "-Wimplicit-function-declaration"
+// compiler flags to their projects to be warned when a function is being
+// used without a prototype in scope.
+
+// These settings are particular to each product.
+// Platform: MacOSX
+// #undef __DARWIN_ONLY_UNIX_CONFORMANCE (automatically set for 64-bit)
+
+// The __DARWIN_ALIAS macros are used to do symbol renaming; they allow
+// legacy code to use the old symbol, thus maintaining binary compatibility
+// while new code can use a standards compliant version of the same function.
+//
+// __DARWIN_ALIAS is used by itself if the function signature has not
+// changed, it is used along with a #ifdef check for __DARWIN_UNIX03
+// if the signature has changed.  Because the __LP64__ environment
+// only supports UNIX03 semantics it causes __DARWIN_UNIX03 to be
+// defined, but causes __DARWIN_ALIAS to do no symbol mangling.
+//
+// As a special case, when XCode is used to target a specific version of the
+// OS, the manifest constant __ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__
+// will be defined by the compiler, with the digits representing major version
+// time 100 + minor version times 10 (e.g. 10.5 := 1050).  If we are targeting
+// pre-10.5, and it is the default compilation environment, revert the
+// compilation environment to pre-__DARWIN_UNIX03.

+//     These macros are for use in OS header files. They enable function prototypes
+//     and Objective-C methods to be tagged with the OS version in which they
+//     were first available; and, if applicable, the OS version in which they
+//     became deprecated.
+//
+//     The desktop Mac OS X and iOS each have different version numbers.
+//     The __OSX_AVAILABLE_STARTING() macro allows you to specify both the desktop
+//     and iOS version numbers.  For instance:
+//         __OSX_AVAILABLE_STARTING(__MAC_10_2,__IPHONE_2_0)
+//     means the function/method was first available on Mac OS X 10.2 on the desktop
+//     and first available in iOS 2.0 on the iPhone.
+//
+//     If a function is available on one platform, but not the other a _NA (not
+//     applicable) parameter is used.  For instance:
+//             __OSX_AVAILABLE_STARTING(__MAC_10_3,__IPHONE_NA)
+//     means that the function/method was first available on Mac OS X 10.3, and it
+//     currently not implemented on the iPhone.
+//
+//     At some point, a function/method may be deprecated.  That means Apple
+//     recommends applications stop using the function, either because there is a
+//     better replacement or the functionality is being phased out.  Deprecated
+//     functions/methods can be tagged with a __OSX_AVAILABLE_BUT_DEPRECATED()
+//     macro which specifies the OS version where the function became available
+//     as well as the OS version in which it became deprecated.  For instance:
+//         __OSX_AVAILABLE_BUT_DEPRECATED(__MAC_10_0,__MAC_10_5,__IPHONE_NA,__IPHONE_NA)
+//     means that the function/method was introduced in Mac OS X 10.0, then
+//     became deprecated beginning in Mac OS X 10.5.  On iOS the function
+//     has never been available.
+//
+//     For these macros to function properly, a program must specify the OS version range
+//     it is targeting.  The min OS version is specified as an option to the compiler:
+//     -mmacosx-version-min=10.x when building for Mac OS X, and -miphoneos-version-min=y.z
+//     when building for the iPhone.  The upper bound for the OS version is rarely needed,
+//     but it can be set on the command line via: -D__MAC_OS_X_VERSION_MAX_ALLOWED=10x0 for
+//     Mac OS X and __IPHONE_OS_VERSION_MAX_ALLOWED = y0z00 for iOS.
+//
+//     Examples:
+//
+//         A function available in Mac OS X 10.5 and later, but not on the phone:
+//
+//             extern void mymacfunc() __OSX_AVAILABLE_STARTING(__MAC_10_5,__IPHONE_NA);
+//
+//
+//         An Objective-C method in Mac OS X 10.5 and later, but not on the phone:
+//
+//             @interface MyClass : NSObject
+//             -(void) mymacmethod __OSX_AVAILABLE_STARTING(__MAC_10_5,__IPHONE_NA);
+//             @end
+//
+//
+//         An enum available on the phone, but not available on Mac OS X:
+//
+//             #if __IPHONE_OS_VERSION_MIN_REQUIRED
+//                 enum { myEnum = 1 };
+//             #endif
+//            Note: this works when targeting the Mac OS X platform because
+//            __IPHONE_OS_VERSION_MIN_REQUIRED is undefined which evaluates to zero.
+//
+//
+//         An enum with values added in different iPhoneOS versions:
+//
+// 			enum {
+// 			    myX  = 1,	// Usable on iPhoneOS 2.1 and later
+// 			    myY  = 2,	// Usable on iPhoneOS 3.0 and later
+// 			    myZ  = 3,	// Usable on iPhoneOS 3.0 and later
+// 				...
+// 		      Note: you do not want to use #if with enumeration values
+// 			  when a client needs to see all values at compile time
+// 			  and use runtime logic to only use the viable values.
+//
+//
+//     It is also possible to use the *_VERSION_MIN_REQUIRED in source code to make one
+//     source base that can be compiled to target a range of OS versions.  It is best
+//     to not use the _MAC_* and __IPHONE_* macros for comparisons, but rather their values.
+//     That is because you might get compiled on an old OS that does not define a later
+//     OS version macro, and in the C preprocessor undefined values evaluate to zero
+//     in expresssions, which could cause the #if expression to evaluate in an unexpected
+//     way.

+
+// This SDK is designed to work with clang and specific versions of
+// gcc >= 4.0 with Apple's patch sets
+
+// Compatibility with compilers and environments that don't support compiler
+// feature checking function-like macros.
+
+// The __CONCAT macro is used to concatenate parts of symbol names, e.g.
+// with "#define OLD(foo) __CONCAT(old,foo)", OLD(foo) produces oldfoo.
+// The __CONCAT macro is a bit tricky -- make sure you don't put spaces
+// in between its arguments.  __CONCAT can also concatenate double-quoted
+// strings produced by the __STRING macro, but this only works with ANSI C.
+
+// __unused denotes variables and functions that may not be used, preventing
+// the compiler from warning about it if not used.
+
+// __used forces variables and functions to be included even if it appears
+// to the compiler that they are not used (and would thust be discarded).
+
+// __cold marks code used for debugging or that is rarely taken
+// and tells the compiler to optimize for size and outline code.
+
+// __exported denotes symbols that should be exported even when symbols
+// are hidden by default.
+// __exported_push/_exported_pop are pragmas used to delimit a range of
+//  symbols that should be exported even when symbols are hidden by default.
+
+// __deprecated causes the compiler to produce a warning when encountering
+// code using the deprecated functionality.
+// __deprecated_msg() does the same, and compilers that support it will print
+// a message along with the deprecation warning.
+// This may require turning on such warning with the -Wdeprecated flag.
+// __deprecated_enum_msg() should be used on enums, and compilers that support
+// it will print the deprecation warning.
+// __kpi_deprecated() specifically indicates deprecation of kernel programming
+// interfaces in Kernel.framework used by KEXTs.
+
+// __unavailable causes the compiler to error out when encountering
+// code using the tagged function
+
+// Delete pseudo-keywords wherever they are not available or needed.
+
+// We use `__restrict' as a way to define the `restrict' type qualifier
+// without disturbing older software that is unaware of C99 keywords.
+
+// Compatibility with compilers and environments that don't support the
+// nullability feature.
+
+// __disable_tail_calls causes the compiler to not perform tail call
+// optimization inside the marked function.
+
+// __not_tail_called causes the compiler to prevent tail call optimization
+// on statically bound calls to the function.  It has no effect on indirect
+// calls.  Virtual functions, objective-c methods, and functions marked as
+// "always_inline" cannot be marked as __not_tail_called.
+
+// __result_use_check warns callers of a function that not using the function
+// return value is a bug, i.e. dismissing malloc() return value results in a
+// memory leak.
+
+// __swift_unavailable causes the compiler to mark a symbol as specifically
+// unavailable in Swift, regardless of any other availability in C.
+
+// __abortlike is the attribute to put on functions like abort() that are
+// typically used to mark assertions. These optimize the codegen
+// for outlining while still maintaining debugability.
+
+// Declaring inline functions within headers is error-prone due to differences
+// across various versions of the C language and extensions.  __header_inline
+// can be used to declare inline functions within system headers.  In cases
+// where you want to force inlining instead of letting the compiler make
+// the decision, you can use __header_always_inline.
+//
+// Be aware that using inline for functions which compilers may also provide
+// builtins can behave differently under various compilers.  If you intend to
+// provide an inline version of such a function, you may want to use a macro
+// instead.
+//
+// The check for !__GNUC__ || __clang__ is because gcc doesn't correctly
+// support c99 inline in some cases:
+// http://gcc.gnu.org/bugzilla/show_bug.cgi?id=55965
+
+// Compiler-dependent macros that bracket portions of code where the
+// "-Wunreachable-code" warning should be ignored. Please use sparingly.
+
+// Compiler-dependent macros to declare that functions take printf-like
+// or scanf-like arguments.  They are null except for versions of gcc
+// that are known to support the features properly.  Functions declared
+// with these attributes will cause compilation warnings if there is a
+// mismatch between the format string and subsequent function parameter
+// types.
+
+// Source compatibility only, ID string not emitted in object file
+
+// __alloc_size can be used to label function arguments that represent the
+// size of memory that the function allocates and returns. The one-argument
+// form labels a single argument that gives the allocation size (where the
+// arguments are numbered from 1):
+//
+// void	*malloc(size_t __size) __alloc_size(1);
+//
+// The two-argument form handles the case where the size is calculated as the
+// product of two arguments:
+//
+// void	*calloc(size_t __count, size_t __size) __alloc_size(1,2);
+
+// COMPILATION ENVIRONMENTS -- see compat(5) for additional detail
+//
+// DEFAULT	By default newly complied code will get POSIX APIs plus
+//		Apple API extensions in scope.
+//
+//		Most users will use this compilation environment to avoid
+//		behavioral differences between 32 and 64 bit code.
+//
+// LEGACY	Defining _NONSTD_SOURCE will get pre-POSIX APIs plus Apple
+//		API extensions in scope.
+//
+//		This is generally equivalent to the Tiger release compilation
+//		environment, except that it cannot be applied to 64 bit code;
+//		its use is discouraged.
+//
+//		We expect this environment to be deprecated in the future.
+//
+// STRICT	Defining _POSIX_C_SOURCE or _XOPEN_SOURCE restricts the
+//		available APIs to exactly the set of APIs defined by the
+//		corresponding standard, based on the value defined.
+//
+//		A correct, portable definition for _POSIX_C_SOURCE is 200112L.
+//		A correct, portable definition for _XOPEN_SOURCE is 600L.
+//
+//		Apple API extensions are not visible in this environment,
+//		which can cause Apple specific code to fail to compile,
+//		or behave incorrectly if prototypes are not in scope or
+//		warnings about missing prototypes are not enabled or ignored.
+//
+// In any compilation environment, for correct symbol resolution to occur,
+// function prototypes must be in scope.  It is recommended that all Apple
+// tools users add either the "-Wall" or "-Wimplicit-function-declaration"
+// compiler flags to their projects to be warned when a function is being
+// used without a prototype in scope.
+
+// These settings are particular to each product.
+// Platform: MacOSX
+
+// The __DARWIN_ALIAS macros are used to do symbol renaming; they allow
+// legacy code to use the old symbol, thus maintaining binary compatibility
+// while new code can use a standards compliant version of the same function.
+//
+// __DARWIN_ALIAS is used by itself if the function signature has not
+// changed, it is used along with a #ifdef check for __DARWIN_UNIX03
+// if the signature has changed.  Because the __LP64__ environment
+// only supports UNIX03 semantics it causes __DARWIN_UNIX03 to be
+// defined, but causes __DARWIN_ALIAS to do no symbol mangling.
+//
+// As a special case, when XCode is used to target a specific version of the
+// OS, the manifest constant __ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__
+// will be defined by the compiler, with the digits representing major version
+// time 100 + minor version times 10 (e.g. 10.5 := 1050).  If we are targeting
+// pre-10.5, and it is the default compilation environment, revert the
+// compilation environment to pre-__DARWIN_UNIX03.

+// header file is included.  This permits us to convert values for feature
+// testing, as necessary, using only _POSIX_C_SOURCE.

+//  _POSIX_C_SOURCE == 200809L		1003.1-2008
+//
+// In addition, the X/Open Portability Guide, which is now the Single UNIX

+//
+//  Public darwin-specific feature macros
+//
+
+// _DARWIN_FEATURE_64_BIT_INODE indicates that the ino_t type is 64-bit, and
+// structures modified for 64-bit inodes (like struct stat) will be used.
+
+// _DARWIN_FEATURE_64_ONLY_BIT_INODE indicates that the ino_t type may only
+// be 64-bit; there is no support for 32-bit ino_t when this macro is defined
+// (and non-zero).  There is no struct stat64 either, as the regular
+// struct stat will already be the 64-bit version.
+
+// _DARWIN_FEATURE_ONLY_VERS_1050 indicates that only those APIs updated
+// in 10.5 exists; no pre-10.5 variants are available.
+
+// _DARWIN_FEATURE_ONLY_UNIX_CONFORMANCE indicates only UNIX conforming API
+// are available (the legacy BSD APIs are not available)
+
+// _DARWIN_FEATURE_UNIX_CONFORMANCE indicates whether UNIX conformance is on,
+// and specifies the conformance level (3 is SUSv3)
+
+// This macro casts away the qualifier from the variable
+//
+// Note: use at your own risk, removing qualifiers can result in
+// catastrophic run-time failures.
+
+// __XNU_PRIVATE_EXTERN is a linkage decoration indicating that a symbol can be
+// used from other compilation units, but not other libraries or executables.
+
+// Architecture validation for current SDK
+
+// Similar to OS_ENUM/OS_CLOSED_ENUM/OS_OPTIONS/OS_CLOSED_OPTIONS
+//
+// This provides more advanced type checking on compilers supporting
+// the proper extensions, even in C.

+// $FreeBSD$
+
+// Testing against Clang-specific extensions.
+
+// This code has been put in place to help reduce the addition of
+// compiler specific defines in FreeBSD code.  It helps to aid in
+// having a compiler-agnostic source tree.
+
+// Compiler memory barriers, specific to gcc and clang.
+
+// XXX: if __GNUC__ >= 2: not tested everywhere originally, where replaced
+
+// Macro to test if we're using a specific version of gcc or later.
+
+// The __CONCAT macro is used to concatenate parts of symbol names, e.g.
+// with "#define OLD(foo) __CONCAT(old,foo)", OLD(foo) produces oldfoo.
+// The __CONCAT macro is a bit tricky to use if it must work in non-ANSI
+// mode -- there must be no spaces between its arguments, and for nested
+// __CONCAT's, all the __CONCAT's must be at the left.  __CONCAT can also
+// concatenate double-quoted strings produced by the __STRING macro, but
+// this only works with ANSI C.
+//
+// __XSTRING is like __STRING, but it expands any macros in its argument
+// first.  It is only available with ANSI C.
+
+// Compiler-dependent macros to help declare dead (non-returning) and
+// pure (no side effects) functions, and unused variables.  They are
+// null except for versions of gcc that are known to support the features
+// properly (old versions of gcc-2 supported the dead and pure features
+// in a different (wrong) way).  If we do not provide an implementation
+// for a given compiler, let the compile fail if it is told to use
+// a feature that we cannot live without.
+
+// Keywords added in C11.
+
+// Emulation of C11 _Generic().  Unlike the previously defined C11
+// keywords, it is not possible to implement this using exactly the same
+// syntax.  Therefore implement something similar under the name
+// __generic().  Unlike _Generic(), this macro can only distinguish
+// between a single type, so it requires nested invocations to
+// distinguish multiple cases.
+
+// C99 Static array indices in function parameter declarations.  Syntax such as:
+// void bar(int myArray[static 10]);
+// is allowed in C99 but not in C++.  Define __min_size appropriately so
+// headers using it can be compiled in either language.  Use like this:
+// void bar(int myArray[__min_size(10)]);
+
+// XXX: should use `#if __STDC_VERSION__ < 199901'.
+
+// C++11 exposes a load of C99 stuff
+
+// GCC 2.95 provides `__restrict' as an extension to C90 to support the
+// C99-specific `restrict' type qualifier.  We happen to use `__restrict' as
+// a way to define the `restrict' type qualifier without disturbing older
+// software that is unaware of C99 keywords.
+
+// GNU C version 2.96 adds explicit branch prediction so that
+// the CPU back-end can hint the processor and also so that
+// code blocks can be reordered such that the predicted path
+// sees a more linear flow, thus improving cache behavior, etc.
+//
+// The following two macros provide us with a way to utilize this
+// compiler feature.  Use __predict_true() if you expect the expression
+// to evaluate to true, and __predict_false() if you expect the
+// expression to evaluate to false.
+//
+// A few notes about usage:
+//
+//	* Generally, __predict_false() error condition checks (unless
+//	  you have some _strong_ reason to do otherwise, in which case
+//	  document it), and/or __predict_true() `no-error' condition
+//	  checks, assuming you want to optimize for the no-error case.
+//
+//	* Other than that, if you don't know the likelihood of a test
+//	  succeeding from empirical or other `hard' evidence, don't
+//	  make predictions.
+//
+//	* These are meant to be used in places that are run `a lot'.
+//	  It is wasteful to make predictions in code that is run
+//	  seldomly (e.g. at subsystem initialization time) as the
+//	  basic block reordering that this affects can often generate
+//	  larger code.
+
+// We define this here since <stddef.h>, <sys/queue.h>, and <sys/types.h>
+// require it.
+
+// Given the pointer x to the member m of the struct s, return
+// a pointer to the containing structure.  When using GCC, we first
+// assign pointer x to a local variable, to check that its type is
+// compatible with member m.
+
+// Compiler-dependent macros to declare that functions take printf-like
+// or scanf-like arguments.  They are null except for versions of gcc
+// that are known to support the features properly (old versions of gcc-2
+// didn't permit keeping the keywords out of the application namespace).
+
+// Compiler-dependent macros that rely on FreeBSD-specific extensions.
+
+// Embed the rcs id of a source file in the resulting library.  Note that in
+// more recent ELF binutils, we use .ident allowing the ID to be stripped.
+// Usage:
+//	__FBSDID("$FreeBSD$");
+
+// -
+// The following definitions are an extension of the behavior originally
+// implemented in <sys/_posix.h>, but with a different level of granularity.
+// POSIX.1 requires that the macros we test be defined before any standard
+// header file is included.
+//
+// Here's a quick run-down of the versions:
+//  defined(_POSIX_SOURCE)		1003.1-1988
+//  _POSIX_C_SOURCE == 1		1003.1-1990
+//  _POSIX_C_SOURCE == 2		1003.2-1992 C Language Binding Option
+//  _POSIX_C_SOURCE == 199309		1003.1b-1993
+//  _POSIX_C_SOURCE == 199506		1003.1c-1995, 1003.1i-1995,
+//					and the omnibus ISO/IEC 9945-1: 1996
+//  _POSIX_C_SOURCE == 200112		1003.1-2001
+//  _POSIX_C_SOURCE == 200809		1003.1-2008
+//
+// In addition, the X/Open Portability Guide, which is now the Single UNIX
+// Specification, defines a feature-test macro which indicates the version of
+// that specification, and which subsumes _POSIX_C_SOURCE.
+//
+// Our macros begin with two underscores to avoid namespace screwage.
+
+// Deal with IEEE Std. 1003.1-1990, in which _POSIX_C_SOURCE == 1.
+
+// Deal with IEEE Std. 1003.2-1992, in which _POSIX_C_SOURCE == 2.
+
+// Deal with various X/Open Portability Guides and Single UNIX Spec.
+
+// Deal with all versions of POSIX.  The ordering relative to the tests above is
+// important.
+// -
+// Deal with _ANSI_SOURCE:
+// If it is defined, and no other compilation environment is explicitly
+// requested, then define our internal feature-test macros to zero.  This
+// makes no difference to the preprocessor (undefined symbols in preprocessing
+// expressions are defined to have value zero), but makes it more convenient for
+// a test program to print out the values.
+//
+// If a program mistakenly defines _ANSI_SOURCE and some other macro such as
+// _POSIX_C_SOURCE, we will assume that it wants the broader compilation
+// environment (and in fact we will never get here).
+
+// User override __EXT1_VISIBLE
+
+// Old versions of GCC use non-standard ARM arch symbols; acle-compat.h
+// translates them to __ARM_ARCH and the modern feature symbols defined by ARM.
+
+// Nullability qualifiers: currently only supported by Clang.
+
+// Type Safety Checking
+//
+// Clang provides additional attributes to enable checking type safety
+// properties that cannot be enforced by the C type system.
+
+// Lock annotations.
+//
+// Clang provides support for doing basic thread-safety tests at
+// compile-time, by marking which locks will/should be held when
+// entering/leaving a functions.
+//
+// Furthermore, it is also possible to annotate variables and structure
+// members to enforce that they are only accessed when certain locks are
+// held.
+
+// Structure implements a lock.
+
+// Function acquires an exclusive or shared lock.
+
+// Function attempts to acquire an exclusive or shared lock.
+
+// Function releases a lock.
+
+// Function asserts that an exclusive or shared lock is held.
+
+// Function requires that an exclusive or shared lock is or is not held.
+
+// Function should not be analyzed.
+
+// Function or variable should not be sanitized, i.e. by AddressSanitizer.
+// GCC has the nosanitize attribute, but as a function attribute only, and
+// warns on use as a variable attribute.
+
+// Guard variables and structure members by lock.

+// long double is distinct from double, so there is nothing to
+//    define here.
+
+// This header should be included at the bottom of each bits/floatn.h.
+//    It defines the following macros for each _FloatN and _FloatNx type,
+//    where the same definitions, or definitions based only on the macros
+//    in bits/floatn.h, are appropriate for all glibc configurations.
+
+// Defined to 1 if the current compiler invocation provides a
+//    floating-point type with the right format for this type, and this
+//    glibc includes corresponding *fN or *fNx interfaces for it.
+
+// Defined to 1 if the corresponding __HAVE_<type> macro is 1 and the
+//    type is the first with its format in the sequence of (the default
+//    choices for) float, double, long double, _Float16, _Float32,
+//    _Float64, _Float128, _Float32x, _Float64x, _Float128x for this
+//    glibc; that is, if functions present once per floating-point format
+//    rather than once per type are present for this type.
+//
+//    All configurations supported by glibc have _Float32 the same format
+//    as float, _Float64 and _Float32x the same format as double, the
+//    _Float64x the same format as either long double or _Float128.  No
+//    configurations support _Float128x or, as of GCC 7, have compiler
+//    support for a type meeting the requirements for _Float128x.
+
+// Defined to 1 if the corresponding _FloatN type is not binary compatible
+//    with the corresponding ISO C type in the current compilation unit as
+//    opposed to __HAVE_DISTINCT_FLOATN, which indicates the default types built
+//    in glibc.
+
+// Defined to 1 if any _FloatN or _FloatNx types that are not
+//    ABI-distinct are however distinct types at the C language level (so
+//    for the purposes of __builtin_types_compatible_p and _Generic).
+
+// Defined to concatenate the literal suffix to be used with _FloatN
+//    or _FloatNx types, if __HAVE_<type> is 1.  The corresponding
+//    literal suffixes exist since GCC 7, for C only.
+
+// Defined to a complex type if __HAVE_<type> is 1.
+
+// The remaining of this file provides support for older compilers.
+
+// If double, long double and _Float64 all have the same set of
+//    values, TS 18661-3 requires the usual arithmetic conversions on
+//    long double and _Float64 to produce _Float64.  For this to be the
+//    case when building with a compiler without a distinct _Float64
+//    type, _Float64 must be a typedef for long double, not for
+//    double.

+//    We define __S<SIZE>_TYPE and __U<SIZE>_TYPE for the signed and unsigned
+//    variants of each of the following integer types on this machine.
+//
+// 	16		-- "natural" 16-bit type (always short)
+// 	32		-- "natural" 32-bit type (always int)
+// 	64		-- "natural" 64-bit type (long or long long)
+// 	LONG32		-- 32-bit type, traditionally long
+// 	QUAD		-- 64-bit type, traditionally long long
+// 	WORD		-- natural type of __WORDSIZE bits (int or long)
+// 	LONGWORD	-- type of __WORDSIZE bits, traditionally long
+//
+//    We distinguish WORD/LONGWORD, 32/LONG32, and 64/QUAD so that the
+//    conventional uses of `long' or `long long' type modifiers match the
+//    types we define, even when a less-adorned type would be the same size.
+//    This matters for (somewhat) portably writing printf/scanf formats for
+//    these types, where using the appropriate l or ll format modifiers can
+//    make the typedefs and the formats match up across all GNU platforms.  If
+//    we used `long' when it's 64 bits where `long long' is expected, then the
+//    compiler would warn about the formats not matching the argument types,
+//    and the programmer changing them to shut up the compiler would break the
+//    program's portability.
+//
+//    Here we assume what is presently the case in all the GCC configurations
+//    we support: long long is always 64 bits, long is always word/address size,
+//    and int is always 32 bits.
+
+// We want __extension__ before typedef's that use nonstandard base types
+//    such as `long long' in C89 mode.

+//    invoke them so that the type is defined as expected.

+// long double is distinct from double, so there is nothing to
+//    define here.
+
+// This header should be included at the bottom of each bits/floatn.h.
+//    It defines the following macros for each _FloatN and _FloatNx type,
+//    where the same definitions, or definitions based only on the macros
+//    in bits/floatn.h, are appropriate for all glibc configurations.
+
+// Defined to 1 if the current compiler invocation provides a
+//    floating-point type with the right format for this type, and this
+//    glibc includes corresponding *fN or *fNx interfaces for it.
+
+// Defined to 1 if the corresponding __HAVE_<type> macro is 1 and the
+//    type is the first with its format in the sequence of (the default
+//    choices for) float, double, long double, _Float16, _Float32,
+//    _Float64, _Float128, _Float32x, _Float64x, _Float128x for this
+//    glibc; that is, if functions present once per floating-point format
+//    rather than once per type are present for this type.
+//
+//    All configurations supported by glibc have _Float32 the same format
+//    as float, _Float64 and _Float32x the same format as double, the
+//    _Float64x the same format as either long double or _Float128.  No
+//    configurations support _Float128x or, as of GCC 7, have compiler
+//    support for a type meeting the requirements for _Float128x.
+
+// Defined to 1 if the corresponding _FloatN type is not binary compatible
+//    with the corresponding ISO C type in the current compilation unit as
+//    opposed to __HAVE_DISTINCT_FLOATN, which indicates the default types built
+//    in glibc.
+
+// Defined to 1 if any _FloatN or _FloatNx types that are not
+//    ABI-distinct are however distinct types at the C language level (so
+//    for the purposes of __builtin_types_compatible_p and _Generic).
+
+// Defined to concatenate the literal suffix to be used with _FloatN
+//    or _FloatNx types, if __HAVE_<type> is 1.  The corresponding
+//    literal suffixes exist since GCC 7, for C only.
+
+// Defined to a complex type if __HAVE_<type> is 1.
+
+// The remaining of this file provides support for older compilers.
+
+// If double, long double and _Float64 all have the same set of
+//    values, TS 18661-3 requires the usual arithmetic conversions on
+//    long double and _Float64 to produce _Float64.  For this to be the
+//    case when building with a compiler without a distinct _Float64
+//    type, _Float64 must be a typedef for long double, not for
+//    double.

+//    We define __S<SIZE>_TYPE and __U<SIZE>_TYPE for the signed and unsigned
+//    variants of each of the following integer types on this machine.
+//
+// 	16		-- "natural" 16-bit type (always short)
+// 	32		-- "natural" 32-bit type (always int)
+// 	64		-- "natural" 64-bit type (long or long long)
+// 	LONG32		-- 32-bit type, traditionally long
+// 	QUAD		-- 64-bit type, traditionally long long
+// 	WORD		-- natural type of __WORDSIZE bits (int or long)
+// 	LONGWORD	-- type of __WORDSIZE bits, traditionally long
+//
+//    We distinguish WORD/LONGWORD, 32/LONG32, and 64/QUAD so that the
+//    conventional uses of `long' or `long long' type modifiers match the
+//    types we define, even when a less-adorned type would be the same size.
+//    This matters for (somewhat) portably writing printf/scanf formats for
+//    these types, where using the appropriate l or ll format modifiers can
+//    make the typedefs and the formats match up across all GNU platforms.  If
+//    we used `long' when it's 64 bits where `long long' is expected, then the
+//    compiler would warn about the formats not matching the argument types,
+//    and the programmer changing them to shut up the compiler would break the
+//    program's portability.
+//
+//    Here we assume what is presently the case in all the GCC configurations
+//    we support: long long is always 64 bits, long is always word/address size,
+//    and int is always 32 bits.

+//    If __NO_LONG_DOUBLE_MATH is already defined, this header must not

+
+// In the default version of this header, long double is
+//    ABI-compatible with double.
+
+// This header should be included at the bottom of each bits/floatn.h.
+//    It defines the following macros for each _FloatN and _FloatNx type,
+//    where the same definitions, or definitions based only on the macros
+//    in bits/floatn.h, are appropriate for all glibc configurations.
+
+// Defined to 1 if the current compiler invocation provides a
+//    floating-point type with the right format for this type, and this
+//    glibc includes corresponding *fN or *fNx interfaces for it.
+
+// Defined to 1 if the corresponding __HAVE_<type> macro is 1 and the
+//    type is the first with its format in the sequence of (the default
+//    choices for) float, double, long double, _Float16, _Float32,
+//    _Float64, _Float128, _Float32x, _Float64x, _Float128x for this
+//    glibc; that is, if functions present once per floating-point format
+//    rather than once per type are present for this type.
+//
+//    All configurations supported by glibc have _Float32 the same format
+//    as float, _Float64 and _Float32x the same format as double, the
+//    _Float64x the same format as either long double or _Float128.  No
+//    configurations support _Float128x or, as of GCC 7, have compiler
+//    support for a type meeting the requirements for _Float128x.
+
+// Defined to 1 if the corresponding _FloatN type is not binary compatible
+//    with the corresponding ISO C type in the current compilation unit as
+//    opposed to __HAVE_DISTINCT_FLOATN, which indicates the default types built
+//    in glibc.
+
+// Defined to 1 if any _FloatN or _FloatNx types that are not
+//    ABI-distinct are however distinct types at the C language level (so
+//    for the purposes of __builtin_types_compatible_p and _Generic).
+
+// Defined to concatenate the literal suffix to be used with _FloatN
+//    or _FloatNx types, if __HAVE_<type> is 1.  The corresponding

+
+// Defined to a complex type if __HAVE_<type> is 1.

+// 	16		-- "natural" 16-bit type (always short)

+// 	QUAD		-- 64-bit type, traditionally long long
+// 	WORD		-- natural type of __WORDSIZE bits (int or long)
+// 	LONGWORD	-- type of __WORDSIZE bits, traditionally long
+//
+//    We distinguish WORD/LONGWORD, 32/LONG32, and 64/QUAD so that the

+//    types we define, even when a less-adorned type would be the same size.
+//    This matters for (somewhat) portably writing printf/scanf formats for
+//    these types, where using the appropriate l or ll format modifiers can
+//    make the typedefs and the formats match up across all GNU platforms.  If
+//    we used `long' when it's 64 bits where `long long' is expected, then the
+//    compiler would warn about the formats not matching the argument types,
+//    and the programmer changing them to shut up the compiler would break the
+//    program's portability.
+//
+//    Here we assume what is presently the case in all the GCC configurations
+//    we support: long long is always 64 bits, long is always word/address size,
+//    and int is always 32 bits.

+// The machine-dependent file <bits/typesizes.h> defines __*_T_TYPE
+//    macros for each of the OS types we define below.  The definitions
+//    of those macros must use the following macros for underlying types.
+//    We define __S<SIZE>_TYPE and __U<SIZE>_TYPE for the signed and unsigned
+//    variants of each of the following integer types on this machine.
+//
+// 	16		-- "natural" 16-bit type (always short)
+// 	32		-- "natural" 32-bit type (always int)
+// 	64		-- "natural" 64-bit type (long or long long)
+// 	LONG32		-- 32-bit type, traditionally long
+// 	QUAD		-- 64-bit type, traditionally long long
+// 	WORD		-- natural type of __WORDSIZE bits (int or long)
+// 	LONGWORD	-- type of __WORDSIZE bits, traditionally long
+//
+//    We distinguish WORD/LONGWORD, 32/LONG32, and 64/QUAD so that the
+//    conventional uses of `long' or `long long' type modifiers match the
+//    types we define, even when a less-adorned type would be the same size.
+//    This matters for (somewhat) portably writing printf/scanf formats for
+//    these types, where using the appropriate l or ll format modifiers can
+//    make the typedefs and the formats match up across all GNU platforms.  If
+//    we used `long' when it's 64 bits where `long long' is expected, then the
+//    compiler would warn about the formats not matching the argument types,
+//    and the programmer changing them to shut up the compiler would break the
+//    program's portability.
+//
+//    Here we assume what is presently the case in all the GCC configurations
+//    we support: long long is always 64 bits, long is always word/address size,
+//    and int is always 32 bits.
+
+// No need to mark the typedef with __extension__.

+
+// Defined to 1 if the current compiler invocation provides a

+
+// Defined to 1 if the corresponding _FloatN type is not binary compatible
+//    with the corresponding ISO C type in the current compilation unit as
+//    opposed to __HAVE_DISTINCT_FLOATN, which indicates the default types built
+//    in glibc.
+
+// Defined to 1 if any _FloatN or _FloatNx types that are not

+//    We define __S<SIZE>_TYPE and __U<SIZE>_TYPE for the signed and unsigned
+//    variants of each of the following integer types on this machine.
+//
+// 	16		-- "natural" 16-bit type (always short)
+// 	32		-- "natural" 32-bit type (always int)
+// 	64		-- "natural" 64-bit type (long or long long)
+// 	LONG32		-- 32-bit type, traditionally long
+// 	QUAD		-- 64-bit type, traditionally long long
+// 	WORD		-- natural type of __WORDSIZE bits (int or long)
+// 	LONGWORD	-- type of __WORDSIZE bits, traditionally long
+//
+//    We distinguish WORD/LONGWORD, 32/LONG32, and 64/QUAD so that the
+//    conventional uses of `long' or `long long' type modifiers match the
+//    types we define, even when a less-adorned type would be the same size.
+//    This matters for (somewhat) portably writing printf/scanf formats for
+//    these types, where using the appropriate l or ll format modifiers can
+//    make the typedefs and the formats match up across all GNU platforms.  If
+//    we used `long' when it's 64 bits where `long long' is expected, then the
+//    compiler would warn about the formats not matching the argument types,
+//    and the programmer changing them to shut up the compiler would break the
+//    program's portability.
+//
+//    Here we assume what is presently the case in all the GCC configurations
+//    we support: long long is always 64 bits, long is always word/address size,
+//    and int is always 32 bits.
+
+// No need to mark the typedef with __extension__.

+// Feature-test macros are defined by several standards, and allow an

+// Public domain.
+//
+// NOTE: Do not protect this header against multiple inclusion.  Doing
+// so can have subtle side-effects due to header file inclusion order
+// and testing of e.g. _POSIX_SOURCE vs. _POSIX_C_SOURCE.  Instead,
+// protect each CPP macro that we want to supply.
+
+// Feature-test macros are defined by several standards, and allow an
+// application to specify what symbols they want the system headers to
+// expose, and hence what standard they want them to conform to.
+// There are two classes of feature-test macros.  The first class
+// specify complete standards, and if one of these is defined, header
+// files will try to conform to the relevant standard.  They are:
+//
+// ANSI macros:
+// _ANSI_SOURCE			ANSI C89
+//
+// POSIX macros:
+// _POSIX_SOURCE == 1		IEEE Std 1003.1 (version?)
+// _POSIX_C_SOURCE == 1		IEEE Std 1003.1-1990
+// _POSIX_C_SOURCE == 2		IEEE Std 1003.2-1992
+// _POSIX_C_SOURCE == 199309L	IEEE Std 1003.1b-1993
+// _POSIX_C_SOURCE == 199506L	ISO/IEC 9945-1:1996
+// _POSIX_C_SOURCE == 200112L	IEEE Std 1003.1-2001
+// _POSIX_C_SOURCE == 200809L   IEEE Std 1003.1-2008
+//
+// X/Open macros:
+// _XOPEN_SOURCE		System Interfaces and Headers, Issue 4, Ver 2
+// _XOPEN_SOURCE_EXTENDED == 1	XSH4.2 UNIX extensions
+// _XOPEN_SOURCE == 500		System Interfaces and Headers, Issue 5
+// _XOPEN_SOURCE == 520		Networking Services (XNS), Issue 5.2
+// _XOPEN_SOURCE == 600		IEEE Std 1003.1-2001, XSI option
+// _XOPEN_SOURCE == 700		IEEE Std 1003.1-2008, XSI option
+//
+// NetBSD macros:
+// _NETBSD_SOURCE == 1		Make all NetBSD features available.
+//
+// If more than one of these "major" feature-test macros is defined,
+// then the set of facilities provided (and namespace used) is the
+// union of that specified by the relevant standards, and in case of
+// conflict, the earlier standard in the above list has precedence (so
+// if both _POSIX_C_SOURCE and _NETBSD_SOURCE are defined, the version
+// of rename() that's used is the POSIX one).  If none of the "major"
+// feature-test macros is defined, _NETBSD_SOURCE is assumed.
+//
+// There are also "minor" feature-test macros, which enable extra
+// functionality in addition to some base standard.  They should be
+// defined along with one of the "major" macros.  The "minor" macros
+// are:
+//
+// _REENTRANT
+// _ISOC99_SOURCE
+// _ISOC11_SOURCE
+// _LARGEFILE_SOURCE		Large File Support
+//		<http://ftp.sas.com/standards/large.file/x_open.20Mar96.html>
+
+// Definitions for byte order, according to byte significance from low
+// address to high.
+
+// C-family endian-ness definitions

+// Public domain.
+//
+// NOTE: Do not protect this header against multiple inclusion.  Doing
+// so can have subtle side-effects due to header file inclusion order
+// and testing of e.g. _POSIX_SOURCE vs. _POSIX_C_SOURCE.  Instead,
+// protect each CPP macro that we want to supply.
+
+// Feature-test macros are defined by several standards, and allow an
+// application to specify what symbols they want the system headers to
+// expose, and hence what standard they want them to conform to.
+// There are two classes of feature-test macros.  The first class
+// specify complete standards, and if one of these is defined, header
+// files will try to conform to the relevant standard.  They are:
+//
+// ANSI macros:
+// _ANSI_SOURCE			ANSI C89
+//
+// POSIX macros:
+// _POSIX_SOURCE == 1		IEEE Std 1003.1 (version?)
+// _POSIX_C_SOURCE == 1		IEEE Std 1003.1-1990
+// _POSIX_C_SOURCE == 2		IEEE Std 1003.2-1992
+// _POSIX_C_SOURCE == 199309L	IEEE Std 1003.1b-1993
+// _POSIX_C_SOURCE == 199506L	ISO/IEC 9945-1:1996
+// _POSIX_C_SOURCE == 200112L	IEEE Std 1003.1-2001
+// _POSIX_C_SOURCE == 200809L   IEEE Std 1003.1-2008
+//
+// X/Open macros:
+// _XOPEN_SOURCE		System Interfaces and Headers, Issue 4, Ver 2
+// _XOPEN_SOURCE_EXTENDED == 1	XSH4.2 UNIX extensions
+// _XOPEN_SOURCE == 500		System Interfaces and Headers, Issue 5
+// _XOPEN_SOURCE == 520		Networking Services (XNS), Issue 5.2
+// _XOPEN_SOURCE == 600		IEEE Std 1003.1-2001, XSI option
+// _XOPEN_SOURCE == 700		IEEE Std 1003.1-2008, XSI option
+//
+// NetBSD macros:
+// _NETBSD_SOURCE == 1		Make all NetBSD features available.
+//
+// If more than one of these "major" feature-test macros is defined,
+// then the set of facilities provided (and namespace used) is the
+// union of that specified by the relevant standards, and in case of
+// conflict, the earlier standard in the above list has precedence (so
+// if both _POSIX_C_SOURCE and _NETBSD_SOURCE are defined, the version
+// of rename() that's used is the POSIX one).  If none of the "major"
+// feature-test macros is defined, _NETBSD_SOURCE is assumed.
+//
+// There are also "minor" feature-test macros, which enable extra
+// functionality in addition to some base standard.  They should be
+// defined along with one of the "major" macros.  The "minor" macros
+// are:
+//
+// _REENTRANT
+// _ISOC99_SOURCE
+// _ISOC11_SOURCE
+// _LARGEFILE_SOURCE		Large File Support
+//		<http://ftp.sas.com/standards/large.file/x_open.20Mar96.html>

+//
+// NOTE: Do not protect this header against multiple inclusion.  Doing
+// so can have subtle side-effects due to header file inclusion order
+// and testing of e.g. _POSIX_SOURCE vs. _POSIX_C_SOURCE.  Instead,
+// protect each CPP macro that we want to supply.
+
+// Feature-test macros are defined by several standards, and allow an
+// application to specify what symbols they want the system headers to
+// expose, and hence what standard they want them to conform to.
+// There are two classes of feature-test macros.  The first class
+// specify complete standards, and if one of these is defined, header
+// files will try to conform to the relevant standard.  They are:
+//
+// ANSI macros:
+// _ANSI_SOURCE			ANSI C89
+//
+// POSIX macros:
+// _POSIX_SOURCE == 1		IEEE Std 1003.1 (version?)
+// _POSIX_C_SOURCE == 1		IEEE Std 1003.1-1990
+// _POSIX_C_SOURCE == 2		IEEE Std 1003.2-1992
+// _POSIX_C_SOURCE == 199309L	IEEE Std 1003.1b-1993
+// _POSIX_C_SOURCE == 199506L	ISO/IEC 9945-1:1996
+// _POSIX_C_SOURCE == 200112L	IEEE Std 1003.1-2001
+// _POSIX_C_SOURCE == 200809L   IEEE Std 1003.1-2008
+//
+// X/Open macros:
+// _XOPEN_SOURCE		System Interfaces and Headers, Issue 4, Ver 2
+// _XOPEN_SOURCE_EXTENDED == 1	XSH4.2 UNIX extensions
+// _XOPEN_SOURCE == 500		System Interfaces and Headers, Issue 5
+// _XOPEN_SOURCE == 520		Networking Services (XNS), Issue 5.2
+// _XOPEN_SOURCE == 600		IEEE Std 1003.1-2001, XSI option
+// _XOPEN_SOURCE == 700		IEEE Std 1003.1-2008, XSI option
+//
+// NetBSD macros:
+// _NETBSD_SOURCE == 1		Make all NetBSD features available.
+//
+// If more than one of these "major" feature-test macros is defined,
+// then the set of facilities provided (and namespace used) is the
+// union of that specified by the relevant standards, and in case of
+// conflict, the earlier standard in the above list has precedence (so
+// if both _POSIX_C_SOURCE and _NETBSD_SOURCE are defined, the version
+// of rename() that's used is the POSIX one).  If none of the "major"
+// feature-test macros is defined, _NETBSD_SOURCE is assumed.
+//
+// There are also "minor" feature-test macros, which enable extra
+// functionality in addition to some base standard.  They should be
+// defined along with one of the "major" macros.  The "minor" macros
+// are:
+//
+// _REENTRANT
+// _ISOC99_SOURCE
+// _ISOC11_SOURCE
+// _LARGEFILE_SOURCE		Large File Support
+//		<http://ftp.sas.com/standards/large.file/x_open.20Mar96.html>

+//
+// NOTE: Do not protect this header against multiple inclusion.  Doing
+// so can have subtle side-effects due to header file inclusion order
+// and testing of e.g. _POSIX_SOURCE vs. _POSIX_C_SOURCE.  Instead,
+// protect each CPP macro that we want to supply.
+
+// Feature-test macros are defined by several standards, and allow an
+// application to specify what symbols they want the system headers to
+// expose, and hence what standard they want them to conform to.
+// There are two classes of feature-test macros.  The first class
+// specify complete standards, and if one of these is defined, header
+// files will try to conform to the relevant standard.  They are:
+//
+// ANSI macros:
+// _ANSI_SOURCE			ANSI C89
+//
+// POSIX macros:
+// _POSIX_SOURCE == 1		IEEE Std 1003.1 (version?)
+// _POSIX_C_SOURCE == 1		IEEE Std 1003.1-1990
+// _POSIX_C_SOURCE == 2		IEEE Std 1003.2-1992
+// _POSIX_C_SOURCE == 199309L	IEEE Std 1003.1b-1993
+// _POSIX_C_SOURCE == 199506L	ISO/IEC 9945-1:1996
+// _POSIX_C_SOURCE == 200112L	IEEE Std 1003.1-2001
+// _POSIX_C_SOURCE == 200809L   IEEE Std 1003.1-2008
+//
+// X/Open macros:
+// _XOPEN_SOURCE		System Interfaces and Headers, Issue 4, Ver 2
+// _XOPEN_SOURCE_EXTENDED == 1	XSH4.2 UNIX extensions
+// _XOPEN_SOURCE == 500		System Interfaces and Headers, Issue 5
+// _XOPEN_SOURCE == 520		Networking Services (XNS), Issue 5.2
+// _XOPEN_SOURCE == 600		IEEE Std 1003.1-2001, XSI option
+// _XOPEN_SOURCE == 700		IEEE Std 1003.1-2008, XSI option
+//
+// NetBSD macros:
+// _NETBSD_SOURCE == 1		Make all NetBSD features available.
+//
+// If more than one of these "major" feature-test macros is defined,
+// then the set of facilities provided (and namespace used) is the
+// union of that specified by the relevant standards, and in case of
+// conflict, the earlier standard in the above list has precedence (so
+// if both _POSIX_C_SOURCE and _NETBSD_SOURCE are defined, the version
+// of rename() that's used is the POSIX one).  If none of the "major"
+// feature-test macros is defined, _NETBSD_SOURCE is assumed.
+//
+// There are also "minor" feature-test macros, which enable extra
+// functionality in addition to some base standard.  They should be
+// defined along with one of the "major" macros.  The "minor" macros
+// are:
+//
+// _REENTRANT
+// _ISOC99_SOURCE
+// _ISOC11_SOURCE
+// _LARGEFILE_SOURCE		Large File Support
+//		<http://ftp.sas.com/standards/large.file/x_open.20Mar96.html>
+
+// Definitions for byte order, according to byte significance from low
+// address to high.

+// Public domain.
+//
+// NOTE: Do not protect this header against multiple inclusion.  Doing
+// so can have subtle side-effects due to header file inclusion order
+// and testing of e.g. _POSIX_SOURCE vs. _POSIX_C_SOURCE.  Instead,
+// protect each CPP macro that we want to supply.
+
+// Feature-test macros are defined by several standards, and allow an
+// application to specify what symbols they want the system headers to
+// expose, and hence what standard they want them to conform to.
+// There are two classes of feature-test macros.  The first class
+// specify complete standards, and if one of these is defined, header
+// files will try to conform to the relevant standard.  They are:
+//
+// ANSI macros:
+// _ANSI_SOURCE			ANSI C89
+//
+// POSIX macros:
+// _POSIX_SOURCE == 1		IEEE Std 1003.1 (version?)
+// _POSIX_C_SOURCE == 1		IEEE Std 1003.1-1990
+// _POSIX_C_SOURCE == 2		IEEE Std 1003.2-1992
+// _POSIX_C_SOURCE == 199309L	IEEE Std 1003.1b-1993
+// _POSIX_C_SOURCE == 199506L	ISO/IEC 9945-1:1996
+// _POSIX_C_SOURCE == 200112L	IEEE Std 1003.1-2001
+// _POSIX_C_SOURCE == 200809L   IEEE Std 1003.1-2008
+//
+// X/Open macros:
+// _XOPEN_SOURCE		System Interfaces and Headers, Issue 4, Ver 2
+// _XOPEN_SOURCE_EXTENDED == 1	XSH4.2 UNIX extensions
+// _XOPEN_SOURCE == 500		System Interfaces and Headers, Issue 5
+// _XOPEN_SOURCE == 520		Networking Services (XNS), Issue 5.2
+// _XOPEN_SOURCE == 600		IEEE Std 1003.1-2001, XSI option
+// _XOPEN_SOURCE == 700		IEEE Std 1003.1-2008, XSI option
+//
+// NetBSD macros:
+// _NETBSD_SOURCE == 1		Make all NetBSD features available.
+//
+// If more than one of these "major" feature-test macros is defined,
+// then the set of facilities provided (and namespace used) is the
+// union of that specified by the relevant standards, and in case of
+// conflict, the earlier standard in the above list has precedence (so
+// if both _POSIX_C_SOURCE and _NETBSD_SOURCE are defined, the version
+// of rename() that's used is the POSIX one).  If none of the "major"
+// feature-test macros is defined, _NETBSD_SOURCE is assumed.
+//
+// There are also "minor" feature-test macros, which enable extra
+// functionality in addition to some base standard.  They should be
+// defined along with one of the "major" macros.  The "minor" macros
+// are:
+//
+// _REENTRANT
+// _ISOC99_SOURCE
+// _ISOC11_SOURCE
+// _LARGEFILE_SOURCE		Large File Support
+//		<http://ftp.sas.com/standards/large.file/x_open.20Mar96.html>

+// Public domain.
+//
+// NOTE: Do not protect this header against multiple inclusion.  Doing
+// so can have subtle side-effects due to header file inclusion order
+// and testing of e.g. _POSIX_SOURCE vs. _POSIX_C_SOURCE.  Instead,
+// protect each CPP macro that we want to supply.
+
+// Feature-test macros are defined by several standards, and allow an
+// application to specify what symbols they want the system headers to
+// expose, and hence what standard they want them to conform to.
+// There are two classes of feature-test macros.  The first class
+// specify complete standards, and if one of these is defined, header
+// files will try to conform to the relevant standard.  They are:
+//
+// ANSI macros:
+// _ANSI_SOURCE			ANSI C89
+//
+// POSIX macros:
+// _POSIX_SOURCE == 1		IEEE Std 1003.1 (version?)
+// _POSIX_C_SOURCE == 1		IEEE Std 1003.1-1990
+// _POSIX_C_SOURCE == 2		IEEE Std 1003.2-1992
+// _POSIX_C_SOURCE == 199309L	IEEE Std 1003.1b-1993
+// _POSIX_C_SOURCE == 199506L	ISO/IEC 9945-1:1996
+// _POSIX_C_SOURCE == 200112L	IEEE Std 1003.1-2001
+// _POSIX_C_SOURCE == 200809L   IEEE Std 1003.1-2008
+//
+// X/Open macros:
+// _XOPEN_SOURCE		System Interfaces and Headers, Issue 4, Ver 2
+// _XOPEN_SOURCE_EXTENDED == 1	XSH4.2 UNIX extensions
+// _XOPEN_SOURCE == 500		System Interfaces and Headers, Issue 5
+// _XOPEN_SOURCE == 520		Networking Services (XNS), Issue 5.2
+// _XOPEN_SOURCE == 600		IEEE Std 1003.1-2001, XSI option
+// _XOPEN_SOURCE == 700		IEEE Std 1003.1-2008, XSI option
+//
+// NetBSD macros:
+// _NETBSD_SOURCE == 1		Make all NetBSD features available.
+//
+// If more than one of these "major" feature-test macros is defined,
+// then the set of facilities provided (and namespace used) is the
+// union of that specified by the relevant standards, and in case of
+// conflict, the earlier standard in the above list has precedence (so
+// if both _POSIX_C_SOURCE and _NETBSD_SOURCE are defined, the version
+// of rename() that's used is the POSIX one).  If none of the "major"
+// feature-test macros is defined, _NETBSD_SOURCE is assumed.
+//
+// There are also "minor" feature-test macros, which enable extra
+// functionality in addition to some base standard.  They should be
+// defined along with one of the "major" macros.  The "minor" macros
+// are:
+//
+// _REENTRANT
+// _ISOC99_SOURCE
+// _ISOC11_SOURCE
+// _LARGEFILE_SOURCE		Large File Support

+// Written by Klaus Klein <kleink@NetBSD.org>, February 2, 1998.
+// Public domain.
+//
+// NOTE: Do not protect this header against multiple inclusion.  Doing
+// so can have subtle side-effects due to header file inclusion order
+// and testing of e.g. _POSIX_SOURCE vs. _POSIX_C_SOURCE.  Instead,
+// protect each CPP macro that we want to supply.
+
+// Feature-test macros are defined by several standards, and allow an
+// application to specify what symbols they want the system headers to
+// expose, and hence what standard they want them to conform to.
+// There are two classes of feature-test macros.  The first class
+// specify complete standards, and if one of these is defined, header
+// files will try to conform to the relevant standard.  They are:
+//
+// ANSI macros:
+// _ANSI_SOURCE			ANSI C89
+//
+// POSIX macros:
+// _POSIX_SOURCE == 1		IEEE Std 1003.1 (version?)
+// _POSIX_C_SOURCE == 1		IEEE Std 1003.1-1990
+// _POSIX_C_SOURCE == 2		IEEE Std 1003.2-1992
+// _POSIX_C_SOURCE == 199309L	IEEE Std 1003.1b-1993
+// _POSIX_C_SOURCE == 199506L	ISO/IEC 9945-1:1996
+// _POSIX_C_SOURCE == 200112L	IEEE Std 1003.1-2001
+// _POSIX_C_SOURCE == 200809L   IEEE Std 1003.1-2008
+//
+// X/Open macros:
+// _XOPEN_SOURCE		System Interfaces and Headers, Issue 4, Ver 2
+// _XOPEN_SOURCE_EXTENDED == 1	XSH4.2 UNIX extensions
+// _XOPEN_SOURCE == 500		System Interfaces and Headers, Issue 5
+// _XOPEN_SOURCE == 520		Networking Services (XNS), Issue 5.2
+// _XOPEN_SOURCE == 600		IEEE Std 1003.1-2001, XSI option
+// _XOPEN_SOURCE == 700		IEEE Std 1003.1-2008, XSI option
+//
+// NetBSD macros:
+// _NETBSD_SOURCE == 1		Make all NetBSD features available.
+//
+// If more than one of these "major" feature-test macros is defined,
+// then the set of facilities provided (and namespace used) is the
+// union of that specified by the relevant standards, and in case of
+// conflict, the earlier standard in the above list has precedence (so
+// if both _POSIX_C_SOURCE and _NETBSD_SOURCE are defined, the version
+// of rename() that's used is the POSIX one).  If none of the "major"
+// feature-test macros is defined, _NETBSD_SOURCE is assumed.
+//
+// There are also "minor" feature-test macros, which enable extra
+// functionality in addition to some base standard.  They should be
+// defined along with one of the "major" macros.  The "minor" macros
+// are:
+//
+// _REENTRANT
+// _ISOC99_SOURCE
+// _ISOC11_SOURCE
+// _LARGEFILE_SOURCE		Large File Support
+//		<http://ftp.sas.com/standards/large.file/x_open.20Mar96.html>

+// Public domain.
+//
+// NOTE: Do not protect this header against multiple inclusion.  Doing
+// so can have subtle side-effects due to header file inclusion order
+// and testing of e.g. _POSIX_SOURCE vs. _POSIX_C_SOURCE.  Instead,
+// protect each CPP macro that we want to supply.
+
+// Feature-test macros are defined by several standards, and allow an
+// application to specify what symbols they want the system headers to
+// expose, and hence what standard they want them to conform to.
+// There are two classes of feature-test macros.  The first class
+// specify complete standards, and if one of these is defined, header
+// files will try to conform to the relevant standard.  They are:
+//
+// ANSI macros:
+// _ANSI_SOURCE			ANSI C89
+//
+// POSIX macros:
+// _POSIX_SOURCE == 1		IEEE Std 1003.1 (version?)
+// _POSIX_C_SOURCE == 1		IEEE Std 1003.1-1990
+// _POSIX_C_SOURCE == 2		IEEE Std 1003.2-1992
+// _POSIX_C_SOURCE == 199309L	IEEE Std 1003.1b-1993
+// _POSIX_C_SOURCE == 199506L	ISO/IEC 9945-1:1996
+// _POSIX_C_SOURCE == 200112L	IEEE Std 1003.1-2001
+// _POSIX_C_SOURCE == 200809L   IEEE Std 1003.1-2008
+//
+// X/Open macros:
+// _XOPEN_SOURCE		System Interfaces and Headers, Issue 4, Ver 2
+// _XOPEN_SOURCE_EXTENDED == 1	XSH4.2 UNIX extensions
+// _XOPEN_SOURCE == 500		System Interfaces and Headers, Issue 5
+// _XOPEN_SOURCE == 520		Networking Services (XNS), Issue 5.2
+// _XOPEN_SOURCE == 600		IEEE Std 1003.1-2001, XSI option
+// _XOPEN_SOURCE == 700		IEEE Std 1003.1-2008, XSI option
+//
+// NetBSD macros:
+// _NETBSD_SOURCE == 1		Make all NetBSD features available.
+//
+// If more than one of these "major" feature-test macros is defined,
+// then the set of facilities provided (and namespace used) is the
+// union of that specified by the relevant standards, and in case of
+// conflict, the earlier standard in the above list has precedence (so
+// if both _POSIX_C_SOURCE and _NETBSD_SOURCE are defined, the version
+// of rename() that's used is the POSIX one).  If none of the "major"
+// feature-test macros is defined, _NETBSD_SOURCE is assumed.
+//
+// There are also "minor" feature-test macros, which enable extra
+// functionality in addition to some base standard.  They should be
+// defined along with one of the "major" macros.  The "minor" macros
+// are:
+//
+// _REENTRANT
+// _ISOC99_SOURCE
+// _ISOC11_SOURCE
+// _LARGEFILE_SOURCE		Large File Support
+//		<http://ftp.sas.com/standards/large.file/x_open.20Mar96.html>
+
+// Definitions for byte order, according to byte significance from low
+// address to high.

+// Public domain.
+//
+// NOTE: Do not protect this header against multiple inclusion.  Doing
+// so can have subtle side-effects due to header file inclusion order
+// and testing of e.g. _POSIX_SOURCE vs. _POSIX_C_SOURCE.  Instead,
+// protect each CPP macro that we want to supply.
+
+// Feature-test macros are defined by several standards, and allow an
+// application to specify what symbols they want the system headers to
+// expose, and hence what standard they want them to conform to.
+// There are two classes of feature-test macros.  The first class
+// specify complete standards, and if one of these is defined, header
+// files will try to conform to the relevant standard.  They are:
+//
+// ANSI macros:
+// _ANSI_SOURCE			ANSI C89
+//
+// POSIX macros:
+// _POSIX_SOURCE == 1		IEEE Std 1003.1 (version?)
+// _POSIX_C_SOURCE == 1		IEEE Std 1003.1-1990
+// _POSIX_C_SOURCE == 2		IEEE Std 1003.2-1992
+// _POSIX_C_SOURCE == 199309L	IEEE Std 1003.1b-1993
+// _POSIX_C_SOURCE == 199506L	ISO/IEC 9945-1:1996
+// _POSIX_C_SOURCE == 200112L	IEEE Std 1003.1-2001
+// _POSIX_C_SOURCE == 200809L   IEEE Std 1003.1-2008
+//
+// X/Open macros:
+// _XOPEN_SOURCE		System Interfaces and Headers, Issue 4, Ver 2
+// _XOPEN_SOURCE_EXTENDED == 1	XSH4.2 UNIX extensions
+// _XOPEN_SOURCE == 500		System Interfaces and Headers, Issue 5
+// _XOPEN_SOURCE == 520		Networking Services (XNS), Issue 5.2
+// _XOPEN_SOURCE == 600		IEEE Std 1003.1-2001, XSI option
+// _XOPEN_SOURCE == 700		IEEE Std 1003.1-2008, XSI option
+//
+// NetBSD macros:
+// _NETBSD_SOURCE == 1		Make all NetBSD features available.
+//
+// If more than one of these "major" feature-test macros is defined,
+// then the set of facilities provided (and namespace used) is the
+// union of that specified by the relevant standards, and in case of
+// conflict, the earlier standard in the above list has precedence (so
+// if both _POSIX_C_SOURCE and _NETBSD_SOURCE are defined, the version
+// of rename() that's used is the POSIX one).  If none of the "major"
+// feature-test macros is defined, _NETBSD_SOURCE is assumed.
+//
+// There are also "minor" feature-test macros, which enable extra
+// functionality in addition to some base standard.  They should be
+// defined along with one of the "major" macros.  The "minor" macros
+// are:
+//
+// _REENTRANT
+// _ISOC99_SOURCE
+// _ISOC11_SOURCE
+// _LARGEFILE_SOURCE		Large File Support
+//		<http://ftp.sas.com/standards/large.file/x_open.20Mar96.html>

+// Feature-test macros are defined by several standards, and allow an

+// There are two classes of feature-test macros.  The first class

+// files will try to conform to the relevant standard.  They are:
+//
+// ANSI macros:
+// _ANSI_SOURCE			ANSI C89
+//
+// POSIX macros:
+// _POSIX_SOURCE == 1		IEEE Std 1003.1 (version?)
+// _POSIX_C_SOURCE == 1		IEEE Std 1003.1-1990

+// _POSIX_C_SOURCE == 200112L	IEEE Std 1003.1-2001
+// _POSIX_C_SOURCE == 200809L   IEEE Std 1003.1-2008
+//
+// X/Open macros:
+// _XOPEN_SOURCE		System Interfaces and Headers, Issue 4, Ver 2
+// _XOPEN_SOURCE_EXTENDED == 1	XSH4.2 UNIX extensions
+// _XOPEN_SOURCE == 500		System Interfaces and Headers, Issue 5
+// _XOPEN_SOURCE == 520		Networking Services (XNS), Issue 5.2

+// Public domain.
+//
+// NOTE: Do not protect this header against multiple inclusion.  Doing
+// so can have subtle side-effects due to header file inclusion order
+// and testing of e.g. _POSIX_SOURCE vs. _POSIX_C_SOURCE.  Instead,
+// protect each CPP macro that we want to supply.
+
+// Feature-test macros are defined by several standards, and allow an
+// application to specify what symbols they want the system headers to
+// expose, and hence what standard they want them to conform to.
+// There are two classes of feature-test macros.  The first class
+// specify complete standards, and if one of these is defined, header
+// files will try to conform to the relevant standard.  They are:
+//
+// ANSI macros:
+// _ANSI_SOURCE			ANSI C89
+//
+// POSIX macros:
+// _POSIX_SOURCE == 1		IEEE Std 1003.1 (version?)
+// _POSIX_C_SOURCE == 1		IEEE Std 1003.1-1990
+// _POSIX_C_SOURCE == 2		IEEE Std 1003.2-1992
+// _POSIX_C_SOURCE == 199309L	IEEE Std 1003.1b-1993
+// _POSIX_C_SOURCE == 199506L	ISO/IEC 9945-1:1996
+// _POSIX_C_SOURCE == 200112L	IEEE Std 1003.1-2001
+// _POSIX_C_SOURCE == 200809L   IEEE Std 1003.1-2008
+//
+// X/Open macros:
+// _XOPEN_SOURCE		System Interfaces and Headers, Issue 4, Ver 2
+// _XOPEN_SOURCE_EXTENDED == 1	XSH4.2 UNIX extensions
+// _XOPEN_SOURCE == 500		System Interfaces and Headers, Issue 5
+// _XOPEN_SOURCE == 520		Networking Services (XNS), Issue 5.2
+// _XOPEN_SOURCE == 600		IEEE Std 1003.1-2001, XSI option
+// _XOPEN_SOURCE == 700		IEEE Std 1003.1-2008, XSI option
+//
+// NetBSD macros:
+// _NETBSD_SOURCE == 1		Make all NetBSD features available.
+//
+// If more than one of these "major" feature-test macros is defined,
+// then the set of facilities provided (and namespace used) is the
+// union of that specified by the relevant standards, and in case of
+// conflict, the earlier standard in the above list has precedence (so
+// if both _POSIX_C_SOURCE and _NETBSD_SOURCE are defined, the version
+// of rename() that's used is the POSIX one).  If none of the "major"
+// feature-test macros is defined, _NETBSD_SOURCE is assumed.
+//
+// There are also "minor" feature-test macros, which enable extra
+// functionality in addition to some base standard.  They should be
+// defined along with one of the "major" macros.  The "minor" macros
+// are:
+//
+// _REENTRANT
+// _ISOC99_SOURCE
+// _ISOC11_SOURCE
+// _LARGEFILE_SOURCE		Large File Support
+//		<http://ftp.sas.com/standards/large.file/x_open.20Mar96.html>

+// _POSIX_SOURCE == 1		IEEE Std 1003.1 (version?)
+// _POSIX_C_SOURCE == 1		IEEE Std 1003.1-1990
+// _POSIX_C_SOURCE == 2		IEEE Std 1003.2-1992
+// _POSIX_C_SOURCE == 199309L	IEEE Std 1003.1b-1993

+// _POSIX_C_SOURCE == 200809L   IEEE Std 1003.1-2008
+//
+// X/Open macros:
+// _XOPEN_SOURCE		System Interfaces and Headers, Issue 4, Ver 2
+// _XOPEN_SOURCE_EXTENDED == 1	XSH4.2 UNIX extensions
+// _XOPEN_SOURCE == 500		System Interfaces and Headers, Issue 5

+// _XOPEN_SOURCE == 700		IEEE Std 1003.1-2008, XSI option
+//
+// NetBSD macros:

+//
+// If more than one of these "major" feature-test macros is defined,

+// conflict, the earlier standard in the above list has precedence (so

+// of rename() that's used is the POSIX one).  If none of the "major"
+// feature-test macros is defined, _NETBSD_SOURCE is assumed.
+//
+// There are also "minor" feature-test macros, which enable extra
+// functionality in addition to some base standard.  They should be
+// defined along with one of the "major" macros.  The "minor" macros
+// are:
+//

+// Public domain.
+//
+// NOTE: Do not protect this header against multiple inclusion.  Doing
+// so can have subtle side-effects due to header file inclusion order
+// and testing of e.g. _POSIX_SOURCE vs. _POSIX_C_SOURCE.  Instead,
+// protect each CPP macro that we want to supply.
+
+// Feature-test macros are defined by several standards, and allow an
+// application to specify what symbols they want the system headers to
+// expose, and hence what standard they want them to conform to.
+// There are two classes of feature-test macros.  The first class
+// specify complete standards, and if one of these is defined, header
+// files will try to conform to the relevant standard.  They are:
+//
+// ANSI macros:
+// _ANSI_SOURCE			ANSI C89
+//
+// POSIX macros:
+// _POSIX_SOURCE == 1		IEEE Std 1003.1 (version?)
+// _POSIX_C_SOURCE == 1		IEEE Std 1003.1-1990
+// _POSIX_C_SOURCE == 2		IEEE Std 1003.2-1992
+// _POSIX_C_SOURCE == 199309L	IEEE Std 1003.1b-1993
+// _POSIX_C_SOURCE == 199506L	ISO/IEC 9945-1:1996
+// _POSIX_C_SOURCE == 200112L	IEEE Std 1003.1-2001
+// _POSIX_C_SOURCE == 200809L   IEEE Std 1003.1-2008
+//
+// X/Open macros:
+// _XOPEN_SOURCE		System Interfaces and Headers, Issue 4, Ver 2
+// _XOPEN_SOURCE_EXTENDED == 1	XSH4.2 UNIX extensions
+// _XOPEN_SOURCE == 500		System Interfaces and Headers, Issue 5
+// _XOPEN_SOURCE == 520		Networking Services (XNS), Issue 5.2
+// _XOPEN_SOURCE == 600		IEEE Std 1003.1-2001, XSI option
+// _XOPEN_SOURCE == 700		IEEE Std 1003.1-2008, XSI option
+//
+// NetBSD macros:
+// _NETBSD_SOURCE == 1		Make all NetBSD features available.
+//
+// If more than one of these "major" feature-test macros is defined,
+// then the set of facilities provided (and namespace used) is the
+// union of that specified by the relevant standards, and in case of
+// conflict, the earlier standard in the above list has precedence (so
+// if both _POSIX_C_SOURCE and _NETBSD_SOURCE are defined, the version
+// of rename() that's used is the POSIX one).  If none of the "major"
+// feature-test macros is defined, _NETBSD_SOURCE is assumed.
+//
+// There are also "minor" feature-test macros, which enable extra
+// functionality in addition to some base standard.  They should be
+// defined along with one of the "major" macros.  The "minor" macros
+// are:
+//
+// _REENTRANT
+// _ISOC99_SOURCE
+// _ISOC11_SOURCE
+// _LARGEFILE_SOURCE		Large File Support
+//		<http://ftp.sas.com/standards/large.file/x_open.20Mar96.html>

+//    __SIZEOF_PTHREAD_ATTR_T        - size of pthread_attr_t.

+
+// This SDK is designed to work with clang and specific versions of
+// gcc >= 4.0 with Apple's patch sets
+
+// Compatibility with compilers and environments that don't support compiler
+// feature checking function-like macros.
+
+// The __CONCAT macro is used to concatenate parts of symbol names, e.g.
+// with "#define OLD(foo) __CONCAT(old,foo)", OLD(foo) produces oldfoo.
+// The __CONCAT macro is a bit tricky -- make sure you don't put spaces
+// in between its arguments.  __CONCAT can also concatenate double-quoted
+// strings produced by the __STRING macro, but this only works with ANSI C.
+
+// __unused denotes variables and functions that may not be used, preventing
+// the compiler from warning about it if not used.
+
+// __used forces variables and functions to be included even if it appears
+// to the compiler that they are not used (and would thust be discarded).
+
+// __cold marks code used for debugging or that is rarely taken
+// and tells the compiler to optimize for size and outline code.
+
+// __deprecated causes the compiler to produce a warning when encountering
+// code using the deprecated functionality.
+// __deprecated_msg() does the same, and compilers that support it will print
+// a message along with the deprecation warning.
+// This may require turning on such warning with the -Wdeprecated flag.
+// __deprecated_enum_msg() should be used on enums, and compilers that support
+// it will print the deprecation warning.
+// __kpi_deprecated() specifically indicates deprecation of kernel programming
+// interfaces in Kernel.framework used by KEXTs.
+
+// __unavailable causes the compiler to error out when encountering
+// code using the tagged function of variable.
+
+// Delete pseudo-keywords wherever they are not available or needed.
+
+// We use `__restrict' as a way to define the `restrict' type qualifier
+// without disturbing older software that is unaware of C99 keywords.
+
+// Compatibility with compilers and environments that don't support the
+// nullability feature.
+
+// __disable_tail_calls causes the compiler to not perform tail call
+// optimization inside the marked function.
+
+// __not_tail_called causes the compiler to prevent tail call optimization
+// on statically bound calls to the function.  It has no effect on indirect
+// calls.  Virtual functions, objective-c methods, and functions marked as
+// "always_inline" cannot be marked as __not_tail_called.
+
+// __result_use_check warns callers of a function that not using the function
+// return value is a bug, i.e. dismissing malloc() return value results in a
+// memory leak.
+
+// __swift_unavailable causes the compiler to mark a symbol as specifically
+// unavailable in Swift, regardless of any other availability in C.
+
+// __abortlike is the attribute to put on functions like abort() that are
+// typically used to mark assertions. These optimize the codegen
+// for outlining while still maintaining debugability.
+
+// Declaring inline functions within headers is error-prone due to differences
+// across various versions of the C language and extensions.  __header_inline
+// can be used to declare inline functions within system headers.  In cases
+// where you want to force inlining instead of letting the compiler make
+// the decision, you can use __header_always_inline.
+//
+// Be aware that using inline for functions which compilers may also provide
+// builtins can behave differently under various compilers.  If you intend to
+// provide an inline version of such a function, you may want to use a macro
+// instead.
+//
+// The check for !__GNUC__ || __clang__ is because gcc doesn't correctly
+// support c99 inline in some cases:
+// http://gcc.gnu.org/bugzilla/show_bug.cgi?id=55965
+
+// Compiler-dependent macros that bracket portions of code where the
+// "-Wunreachable-code" warning should be ignored. Please use sparingly.
+
+// Compiler-dependent macros to declare that functions take printf-like
+// or scanf-like arguments.  They are null except for versions of gcc
+// that are known to support the features properly.  Functions declared
+// with these attributes will cause compilation warnings if there is a
+// mismatch between the format string and subsequent function parameter
+// types.
+
+// Source compatibility only, ID string not emitted in object file

+// COMPILATION ENVIRONMENTS -- see compat(5) for additional detail
+//
+// DEFAULT	By default newly complied code will get POSIX APIs plus
+//		Apple API extensions in scope.
+//
+//		Most users will use this compilation environment to avoid
+//		behavioral differences between 32 and 64 bit code.
+//
+// LEGACY	Defining _NONSTD_SOURCE will get pre-POSIX APIs plus Apple
+//		API extensions in scope.
+//
+//		This is generally equivalent to the Tiger release compilation
+//		environment, except that it cannot be applied to 64 bit code;
+//		its use is discouraged.
+//
+//		We expect this environment to be deprecated in the future.
+//
+// STRICT	Defining _POSIX_C_SOURCE or _XOPEN_SOURCE restricts the
+//		available APIs to exactly the set of APIs defined by the
+//		corresponding standard, based on the value defined.
+//
+//		A correct, portable definition for _POSIX_C_SOURCE is 200112L.
+//		A correct, portable definition for _XOPEN_SOURCE is 600L.
+//
+//		Apple API extensions are not visible in this environment,
+//		which can cause Apple specific code to fail to compile,
+//		or behave incorrectly if prototypes are not in scope or
+//		warnings about missing prototypes are not enabled or ignored.
+//
+// In any compilation environment, for correct symbol resolution to occur,
+// function prototypes must be in scope.  It is recommended that all Apple
+// tools users add either the "-Wall" or "-Wimplicit-function-declaration"
+// compiler flags to their projects to be warned when a function is being
+// used without a prototype in scope.
+
+// These settings are particular to each product.
+// Platform: MacOSX
+// #undef __DARWIN_ONLY_UNIX_CONFORMANCE (automatically set for 64-bit)
+
+// The __DARWIN_ALIAS macros are used to do symbol renaming; they allow
+// legacy code to use the old symbol, thus maintaining binary compatibility
+// while new code can use a standards compliant version of the same function.
+//
+// __DARWIN_ALIAS is used by itself if the function signature has not
+// changed, it is used along with a #ifdef check for __DARWIN_UNIX03
+// if the signature has changed.  Because the __LP64__ environment
+// only supports UNIX03 semantics it causes __DARWIN_UNIX03 to be
+// defined, but causes __DARWIN_ALIAS to do no symbol mangling.
+//
+// As a special case, when XCode is used to target a specific version of the
+// OS, the manifest constant __ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__
+// will be defined by the compiler, with the digits representing major version
+// time 100 + minor version times 10 (e.g. 10.5 := 1050).  If we are targeting
+// pre-10.5, and it is the default compilation environment, revert the
+// compilation environment to pre-__DARWIN_UNIX03.

+//  Public darwin-specific feature macros
+//
+
+// _DARWIN_FEATURE_64_BIT_INODE indicates that the ino_t type is 64-bit, and
+// structures modified for 64-bit inodes (like struct stat) will be used.
+
+// _DARWIN_FEATURE_64_ONLY_BIT_INODE indicates that the ino_t type may only
+// be 64-bit; there is no support for 32-bit ino_t when this macro is defined
+// (and non-zero).  There is no struct stat64 either, as the regular
+// struct stat will already be the 64-bit version.
+
+// _DARWIN_FEATURE_ONLY_VERS_1050 indicates that only those APIs updated
+// in 10.5 exists; no pre-10.5 variants are available.
+
+// _DARWIN_FEATURE_ONLY_UNIX_CONFORMANCE indicates only UNIX conforming API
+// are available (the legacy BSD APIs are not available)
+
+// _DARWIN_FEATURE_UNIX_CONFORMANCE indicates whether UNIX conformance is on,
+// and specifies the conformance level (3 is SUSv3)
+
+// This macro casts away the qualifier from the variable
+//
+// Note: use at your own risk, removing qualifiers can result in
+// catastrophic run-time failures.
+
+// __XNU_PRIVATE_EXTERN is a linkage decoration indicating that a symbol can be
+// used from other compilation units, but not other libraries or executables.
+
+// Architecture validation for current SDK
+
+// Similar to OS_ENUM/OS_CLOSED_ENUM/OS_OPTIONS/OS_CLOSED_OPTIONS
+//
+// This provides more advanced type checking on compilers supporting
+// the proper extensions, even in C.

+
+// This SDK is designed to work with clang and specific versions of
+// gcc >= 4.0 with Apple's patch sets
+
+// Compatibility with compilers and environments that don't support compiler
+// feature checking function-like macros.
+
+// The __CONCAT macro is used to concatenate parts of symbol names, e.g.
+// with "#define OLD(foo) __CONCAT(old,foo)", OLD(foo) produces oldfoo.
+// The __CONCAT macro is a bit tricky -- make sure you don't put spaces
+// in between its arguments.  __CONCAT can also concatenate double-quoted
+// strings produced by the __STRING macro, but this only works with ANSI C.
+
+// __unused denotes variables and functions that may not be used, preventing
+// the compiler from warning about it if not used.
+
+// __used forces variables and functions to be included even if it appears
+// to the compiler that they are not used (and would thust be discarded).
+
+// __cold marks code used for debugging or that is rarely taken
+// and tells the compiler to optimize for size and outline code.
+
+// __exported denotes symbols that should be exported even when symbols
+// are hidden by default.
+// __exported_push/_exported_pop are pragmas used to delimit a range of
+//  symbols that should be exported even when symbols are hidden by default.
+
+// __deprecated causes the compiler to produce a warning when encountering
+// code using the deprecated functionality.
+// __deprecated_msg() does the same, and compilers that support it will print
+// a message along with the deprecation warning.
+// This may require turning on such warning with the -Wdeprecated flag.
+// __deprecated_enum_msg() should be used on enums, and compilers that support
+// it will print the deprecation warning.
+// __kpi_deprecated() specifically indicates deprecation of kernel programming
+// interfaces in Kernel.framework used by KEXTs.
+
+// __unavailable causes the compiler to error out when encountering
+// code using the tagged function
+
+// Delete pseudo-keywords wherever they are not available or needed.
+
+// We use `__restrict' as a way to define the `restrict' type qualifier
+// without disturbing older software that is unaware of C99 keywords.
+
+// Compatibility with compilers and environments that don't support the
+// nullability feature.
+
+// __disable_tail_calls causes the compiler to not perform tail call
+// optimization inside the marked function.
+
+// __not_tail_called causes the compiler to prevent tail call optimization
+// on statically bound calls to the function.  It has no effect on indirect
+// calls.  Virtual functions, objective-c methods, and functions marked as
+// "always_inline" cannot be marked as __not_tail_called.
+
+// __result_use_check warns callers of a function that not using the function
+// return value is a bug, i.e. dismissing malloc() return value results in a
+// memory leak.
+
+// __swift_unavailable causes the compiler to mark a symbol as specifically
+// unavailable in Swift, regardless of any other availability in C.
+
+// __abortlike is the attribute to put on functions like abort() that are
+// typically used to mark assertions. These optimize the codegen
+// for outlining while still maintaining debugability.
+
+// Declaring inline functions within headers is error-prone due to differences
+// across various versions of the C language and extensions.  __header_inline
+// can be used to declare inline functions within system headers.  In cases
+// where you want to force inlining instead of letting the compiler make
+// the decision, you can use __header_always_inline.
+//
+// Be aware that using inline for functions which compilers may also provide
+// builtins can behave differently under various compilers.  If you intend to
+// provide an inline version of such a function, you may want to use a macro
+// instead.
+//
+// The check for !__GNUC__ || __clang__ is because gcc doesn't correctly
+// support c99 inline in some cases:
+// http://gcc.gnu.org/bugzilla/show_bug.cgi?id=55965
+
+// Compiler-dependent macros that bracket portions of code where the
+// "-Wunreachable-code" warning should be ignored. Please use sparingly.
+
+// Compiler-dependent macros to declare that functions take printf-like
+// or scanf-like arguments.  They are null except for versions of gcc
+// that are known to support the features properly.  Functions declared
+// with these attributes will cause compilation warnings if there is a
+// mismatch between the format string and subsequent function parameter
+// types.
+
+// Source compatibility only, ID string not emitted in object file
+
+// __alloc_size can be used to label function arguments that represent the
+// size of memory that the function allocates and returns. The one-argument
+// form labels a single argument that gives the allocation size (where the
+// arguments are numbered from 1):
+//
+// void	*malloc(size_t __size) __alloc_size(1);
+//
+// The two-argument form handles the case where the size is calculated as the
+// product of two arguments:
+//
+// void	*calloc(size_t __count, size_t __size) __alloc_size(1,2);
+
+// COMPILATION ENVIRONMENTS -- see compat(5) for additional detail
+//
+// DEFAULT	By default newly complied code will get POSIX APIs plus
+//		Apple API extensions in scope.
+//
+//		Most users will use this compilation environment to avoid
+//		behavioral differences between 32 and 64 bit code.
+//
+// LEGACY	Defining _NONSTD_SOURCE will get pre-POSIX APIs plus Apple
+//		API extensions in scope.
+//
+//		This is generally equivalent to the Tiger release compilation
+//		environment, except that it cannot be applied to 64 bit code;
+//		its use is discouraged.
+//
+//		We expect this environment to be deprecated in the future.
+//
+// STRICT	Defining _POSIX_C_SOURCE or _XOPEN_SOURCE restricts the
+//		available APIs to exactly the set of APIs defined by the
+//		corresponding standard, based on the value defined.
+//
+//		A correct, portable definition for _POSIX_C_SOURCE is 200112L.
+//		A correct, portable definition for _XOPEN_SOURCE is 600L.
+//
+//		Apple API extensions are not visible in this environment,
+//		which can cause Apple specific code to fail to compile,
+//		or behave incorrectly if prototypes are not in scope or
+//		warnings about missing prototypes are not enabled or ignored.
+//
+// In any compilation environment, for correct symbol resolution to occur,
+// function prototypes must be in scope.  It is recommended that all Apple
+// tools users add either the "-Wall" or "-Wimplicit-function-declaration"
+// compiler flags to their projects to be warned when a function is being
+// used without a prototype in scope.
+
+// These settings are particular to each product.
+// Platform: MacOSX
+
+// The __DARWIN_ALIAS macros are used to do symbol renaming; they allow
+// legacy code to use the old symbol, thus maintaining binary compatibility
+// while new code can use a standards compliant version of the same function.
+//
+// __DARWIN_ALIAS is used by itself if the function signature has not
+// changed, it is used along with a #ifdef check for __DARWIN_UNIX03
+// if the signature has changed.  Because the __LP64__ environment
+// only supports UNIX03 semantics it causes __DARWIN_UNIX03 to be
+// defined, but causes __DARWIN_ALIAS to do no symbol mangling.
+//
+// As a special case, when XCode is used to target a specific version of the
+// OS, the manifest constant __ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__
+// will be defined by the compiler, with the digits representing major version
+// time 100 + minor version times 10 (e.g. 10.5 := 1050).  If we are targeting
+// pre-10.5, and it is the default compilation environment, revert the
+// compilation environment to pre-__DARWIN_UNIX03.

+//
+// In addition, the X/Open Portability Guide, which is now the Single UNIX

+// the appropriate namespace.  For POSIX, these values will correspond to
+// _POSIX_C_SOURCE value.  Currently there are two additional levels corresponding
+// to ANSI (_ANSI_SOURCE) and Darwin extensions (_DARWIN_C_SOURCE)

+//  Public darwin-specific feature macros
+//
+
+// _DARWIN_FEATURE_64_BIT_INODE indicates that the ino_t type is 64-bit, and
+// structures modified for 64-bit inodes (like struct stat) will be used.
+
+// _DARWIN_FEATURE_64_ONLY_BIT_INODE indicates that the ino_t type may only
+// be 64-bit; there is no support for 32-bit ino_t when this macro is defined
+// (and non-zero).  There is no struct stat64 either, as the regular
+// struct stat will already be the 64-bit version.
+
+// _DARWIN_FEATURE_ONLY_VERS_1050 indicates that only those APIs updated
+// in 10.5 exists; no pre-10.5 variants are available.
+
+// _DARWIN_FEATURE_ONLY_UNIX_CONFORMANCE indicates only UNIX conforming API
+// are available (the legacy BSD APIs are not available)
+
+// _DARWIN_FEATURE_UNIX_CONFORMANCE indicates whether UNIX conformance is on,
+// and specifies the conformance level (3 is SUSv3)
+
+// This macro casts away the qualifier from the variable
+//
+// Note: use at your own risk, removing qualifiers can result in
+// catastrophic run-time failures.
+
+// __XNU_PRIVATE_EXTERN is a linkage decoration indicating that a symbol can be
+// used from other compilation units, but not other libraries or executables.
+
+// Architecture validation for current SDK
+
+// Similar to OS_ENUM/OS_CLOSED_ENUM/OS_OPTIONS/OS_CLOSED_OPTIONS
+//
+// This provides more advanced type checking on compilers supporting
+// the proper extensions, even in C.

+// $FreeBSD$
+
+// Testing against Clang-specific extensions.
+
+// This code has been put in place to help reduce the addition of
+// compiler specific defines in FreeBSD code.  It helps to aid in
+// having a compiler-agnostic source tree.
+
+// Compiler memory barriers, specific to gcc and clang.
+
+// XXX: if __GNUC__ >= 2: not tested everywhere originally, where replaced
+
+// Macro to test if we're using a specific version of gcc or later.
+
+// The __CONCAT macro is used to concatenate parts of symbol names, e.g.
+// with "#define OLD(foo) __CONCAT(old,foo)", OLD(foo) produces oldfoo.
+// The __CONCAT macro is a bit tricky to use if it must work in non-ANSI
+// mode -- there must be no spaces between its arguments, and for nested
+// __CONCAT's, all the __CONCAT's must be at the left.  __CONCAT can also
+// concatenate double-quoted strings produced by the __STRING macro, but
+// this only works with ANSI C.
+//
+// __XSTRING is like __STRING, but it expands any macros in its argument
+// first.  It is only available with ANSI C.
+
+// Compiler-dependent macros to help declare dead (non-returning) and
+// pure (no side effects) functions, and unused variables.  They are
+// null except for versions of gcc that are known to support the features
+// properly (old versions of gcc-2 supported the dead and pure features
+// in a different (wrong) way).  If we do not provide an implementation
+// for a given compiler, let the compile fail if it is told to use
+// a feature that we cannot live without.
+
+// Keywords added in C11.
+
+// Emulation of C11 _Generic().  Unlike the previously defined C11
+// keywords, it is not possible to implement this using exactly the same
+// syntax.  Therefore implement something similar under the name
+// __generic().  Unlike _Generic(), this macro can only distinguish
+// between a single type, so it requires nested invocations to
+// distinguish multiple cases.
+
+// C99 Static array indices in function parameter declarations.  Syntax such as:
+// void bar(int myArray[static 10]);
+// is allowed in C99 but not in C++.  Define __min_size appropriately so
+// headers using it can be compiled in either language.  Use like this:
+// void bar(int myArray[__min_size(10)]);
+
+// XXX: should use `#if __STDC_VERSION__ < 199901'.
+
+// C++11 exposes a load of C99 stuff
+
+// GCC 2.95 provides `__restrict' as an extension to C90 to support the
+// C99-specific `restrict' type qualifier.  We happen to use `__restrict' as
+// a way to define the `restrict' type qualifier without disturbing older
+// software that is unaware of C99 keywords.
+
+// GNU C version 2.96 adds explicit branch prediction so that
+// the CPU back-end can hint the processor and also so that
+// code blocks can be reordered such that the predicted path
+// sees a more linear flow, thus improving cache behavior, etc.
+//
+// The following two macros provide us with a way to utilize this
+// compiler feature.  Use __predict_true() if you expect the expression
+// to evaluate to true, and __predict_false() if you expect the
+// expression to evaluate to false.
+//
+// A few notes about usage:
+//
+//	* Generally, __predict_false() error condition checks (unless
+//	  you have some _strong_ reason to do otherwise, in which case
+//	  document it), and/or __predict_true() `no-error' condition
+//	  checks, assuming you want to optimize for the no-error case.
+//
+//	* Other than that, if you don't know the likelihood of a test
+//	  succeeding from empirical or other `hard' evidence, don't
+//	  make predictions.
+//
+//	* These are meant to be used in places that are run `a lot'.
+//	  It is wasteful to make predictions in code that is run
+//	  seldomly (e.g. at subsystem initialization time) as the
+//	  basic block reordering that this affects can often generate
+//	  larger code.
+
+// We define this here since <stddef.h>, <sys/queue.h>, and <sys/types.h>
+// require it.
+
+// Given the pointer x to the member m of the struct s, return
+// a pointer to the containing structure.  When using GCC, we first
+// assign pointer x to a local variable, to check that its type is
+// compatible with member m.
+
+// Compiler-dependent macros to declare that functions take printf-like
+// or scanf-like arguments.  They are null except for versions of gcc
+// that are known to support the features properly (old versions of gcc-2
+// didn't permit keeping the keywords out of the application namespace).
+
+// Compiler-dependent macros that rely on FreeBSD-specific extensions.
+
+// Embed the rcs id of a source file in the resulting library.  Note that in
+// more recent ELF binutils, we use .ident allowing the ID to be stripped.
+// Usage:
+//	__FBSDID("$FreeBSD$");
+
+// -
+// The following definitions are an extension of the behavior originally
+// implemented in <sys/_posix.h>, but with a different level of granularity.
+// POSIX.1 requires that the macros we test be defined before any standard
+// header file is included.
+//
+// Here's a quick run-down of the versions:
+//  defined(_POSIX_SOURCE)		1003.1-1988
+//  _POSIX_C_SOURCE == 1		1003.1-1990
+//  _POSIX_C_SOURCE == 2		1003.2-1992 C Language Binding Option
+//  _POSIX_C_SOURCE == 199309		1003.1b-1993
+//  _POSIX_C_SOURCE == 199506		1003.1c-1995, 1003.1i-1995,
+//					and the omnibus ISO/IEC 9945-1: 1996
+//  _POSIX_C_SOURCE == 200112		1003.1-2001
+//  _POSIX_C_SOURCE == 200809		1003.1-2008
+//
+// In addition, the X/Open Portability Guide, which is now the Single UNIX
+// Specification, defines a feature-test macro which indicates the version of
+// that specification, and which subsumes _POSIX_C_SOURCE.
+//
+// Our macros begin with two underscores to avoid namespace screwage.
+
+// Deal with IEEE Std. 1003.1-1990, in which _POSIX_C_SOURCE == 1.
+
+// Deal with IEEE Std. 1003.2-1992, in which _POSIX_C_SOURCE == 2.
+
+// Deal with various X/Open Portability Guides and Single UNIX Spec.
+
+// Deal with all versions of POSIX.  The ordering relative to the tests above is
+// important.
+// -
+// Deal with _ANSI_SOURCE:
+// If it is defined, and no other compilation environment is explicitly
+// requested, then define our internal feature-test macros to zero.  This
+// makes no difference to the preprocessor (undefined symbols in preprocessing
+// expressions are defined to have value zero), but makes it more convenient for
+// a test program to print out the values.
+//
+// If a program mistakenly defines _ANSI_SOURCE and some other macro such as
+// _POSIX_C_SOURCE, we will assume that it wants the broader compilation
+// environment (and in fact we will never get here).
+
+// User override __EXT1_VISIBLE
+
+// Old versions of GCC use non-standard ARM arch symbols; acle-compat.h
+// translates them to __ARM_ARCH and the modern feature symbols defined by ARM.
+
+// Nullability qualifiers: currently only supported by Clang.
+
+// Type Safety Checking
+//
+// Clang provides additional attributes to enable checking type safety
+// properties that cannot be enforced by the C type system.
+
+// Lock annotations.
+//
+// Clang provides support for doing basic thread-safety tests at
+// compile-time, by marking which locks will/should be held when
+// entering/leaving a functions.
+//
+// Furthermore, it is also possible to annotate variables and structure
+// members to enforce that they are only accessed when certain locks are
+// held.
+
+// Structure implements a lock.
+
+// Function acquires an exclusive or shared lock.
+
+// Function attempts to acquire an exclusive or shared lock.
+
+// Function releases a lock.
+
+// Function asserts that an exclusive or shared lock is held.
+
+// Function requires that an exclusive or shared lock is or is not held.
+
+// Function should not be analyzed.
+
+// Function or variable should not be sanitized, i.e. by AddressSanitizer.
+// GCC has the nosanitize attribute, but as a function attribute only, and
+// warns on use as a variable attribute.
+
+// Guard variables and structure members by lock.

+//    The `-ansi' switch to the GNU C compiler, and standards conformance

+//
+//    These are defined by this file and are used by the
+//    header files to decide what to declare or define:
+//
+//    __GLIBC_USE (F)	Define things from feature set F.  This is defined
+// 			to 1 or 0; the subsequent macros are either defined
+// 			or undefined, and those tests should be moved to

+//    __USE_ISOCXX11	Define ISO C++11 things.
+//    __USE_POSIX		Define IEEE Std 1003.1 things.
+//    __USE_POSIX2		Define IEEE Std 1003.2 things.
+//    __USE_POSIX199309	Define IEEE Std 1003.1, and .1b things.

+//    __USE_LARGEFILE64	Define LFS things with separate names.
+//    __USE_FILE_OFFSET64	Define 64bit interface as default.
+//    __USE_MISC		Define things from 4.3BSD or System V Unix.
+//    __USE_ATFILE		Define *at interfaces and AT_* constants for them.
+//    __USE_GNU		Define GNU extensions.
+//    __USE_FORTIFY_LEVEL	Additional security measures used, according to level.
+//
+//    The macros `__GNU_LIBRARY__', `__GLIBC__', and `__GLIBC_MINOR__' are
+//    defined by this file unconditionally.  `__GNU_LIBRARY__' is provided
+//    only for compatibility.  All new code should use the other symbols
+//    to test for features.
+//
+//    All macros listed above as possibly being defined by this file are
+//    explicitly undefined if they are not explicitly defined.
+//    Feature-test macros that are not defined by the user or compiler
+//    but are implied by the other feature-test macros defined (or by the
+//    lack of any definitions) are defined by the file.
+//
+//    ISO C feature test macros depend on the definition of the macro
+//    when an affected header is included, not when the first system
+//    header is included, and so they are handled in
+//    <bits/libc-header-start.h>, which does not have a multiple include
+//    guard.  Feature test macros that can be handled from the first
+//    system header included are handled here.
+
+// Undefine everything, so we get a clean slate.
+
+// Suppress kernel-name space pollution unless user expressedly asks
+//    for it.
+
+// Convenience macro to test the version of gcc.
+//    Use like this:
+//    #if __GNUC_PREREQ (2,8)
+//    ... code requiring gcc 2.8 or later ...
+//    #endif
+//    Note: only works for GCC 2.0 and later, because __GNUC_MINOR__ was
+//    added in 2.0.
+
+// Similarly for clang.  Features added to GCC after version 4.2 may
+//    or may not also be available in clang, and clang's definitions of
+//    __GNUC(_MINOR)__ are fixed at 4 and 2 respectively.  Not all such
+//    features can be queried via __has_extension/__has_feature.
+
+// Whether to use feature set F.
+
+// _BSD_SOURCE and _SVID_SOURCE are deprecated aliases for
+//    _DEFAULT_SOURCE.  If _DEFAULT_SOURCE is present we do not
+//    issue a warning; the expectation is that the source is being
+//    transitioned to use the new macro.
+
+// If _GNU_SOURCE was defined by the user, turn on all the other features.
+
+// If nothing (other than _GNU_SOURCE and _DEFAULT_SOURCE) is defined,
+//    define _DEFAULT_SOURCE.
+
+// This is to enable the ISO C2X extension.
+
+// This is to enable the ISO C11 extension.
+
+// This is to enable the ISO C99 extension.
+
+// This is to enable the ISO C90 Amendment 1:1995 extension.
+
+// If none of the ANSI/POSIX macros are defined, or if _DEFAULT_SOURCE
+//    is defined, use POSIX.1-2008 (or another version depending on
+//    _XOPEN_SOURCE).
+
+// Some C libraries once required _REENTRANT and/or _THREAD_SAFE to be
+//    defined in all multithreaded code.  GNU libc has not required this
+//    for many years.  We now treat them as compatibility synonyms for
+//    _POSIX_C_SOURCE=199506L, which is the earliest level of POSIX with
+//    comprehensive support for multithreaded code.  Using them never
+//    lowers the selected level of POSIX conformance, only raises it.
+
+// The function 'gets' existed in C89, but is impossible to use
+//    safely.  It has been removed from ISO C11 and ISO C++14.  Note: for
+//    compatibility with various implementations of <cstdio>, this test
+//    must consider only the value of __cplusplus when compiling C++.
+
+// GNU formerly extended the scanf functions with modified format
+//    specifiers %as, %aS, and %a[...] that allocate a buffer for the
+//    input using malloc.  This extension conflicts with ISO C99, which
+//    defines %a as a standalone format specifier that reads a floating-
+//    point number; moreover, POSIX.1-2008 provides the same feature
+//    using the modifier letter 'm' instead (%ms, %mS, %m[...]).
+//
+//    We now follow C99 unless GNU extensions are active and the compiler
+//    is specifically in C89 or C++98 mode (strict or not).  For
+//    instance, with GCC, -std=gnu11 will have C99-compliant scanf with
+//    or without -D_GNU_SOURCE, but -std=c89 -D_GNU_SOURCE will have the
+//    old extension.

+// We are almost always included from features.h.
+
+// The GNU libc does not support any K&R compilers or the traditional mode
+//    of ISO C compilers anymore.  Check for some of the combinations not
+//    anymore supported.
+
+// Some user header file might have defined this before.
+
+// All functions, except those with callbacks or those that
+//    synchronize memory, are leaf functions.
+
+// GCC can always grok prototypes.  For C++ programs we add throw()
+//    to help it optimize the function calls.  But this works only with
+//    gcc 2.8.x and egcs.  For gcc 3.2 and up we even mark C functions
+//    as non-throwing using a function attribute since programs can use
+//    the -fexceptions options for C code as well.
+
+// Compilers that are not clang may object to
+//        #if defined __clang__ && __has_extension(...)
+//    even though they do not need to evaluate the right-hand side of the &&.
+
+// These two macros are not used in glibc anymore.  They are kept here
+//    only because some other projects expect the macros to be defined.
+
+// For these things, GCC behaves the ANSI way normally,
+//    and the non-ANSI way under -traditional.
+
+// This is not a typedef so `const __ptr_t' does the right thing.
+
+// C++ needs to know that types and declarations are C, not C++.
+
+// Fortify support.
+
+// Support for flexible arrays.
+//    Headers that should use flexible arrays only if they're "real"
+//    (e.g. only if they won't affect sizeof()) should test
+//    #if __glibc_c99_flexarr_available.
+
+// __asm__ ("xyz") is used throughout the headers to rename functions
+//    at the assembly language level.  This is wrapped by the __REDIRECT
+//    macro, in order to support compilers that can do this some other
+//    way.  When compilers don't support asm-names at all, we have to do
+//    preprocessor tricks instead (which don't have exactly the right
+//    semantics, but it's the best we can do).
+//
+//    Example:
+//    int __REDIRECT(setpgrp, (__pid_t pid, __pid_t pgrp), setpgid);
+
+//
+// #elif __SOME_OTHER_COMPILER__
+//
+// # define __REDIRECT(name, proto, alias) name proto; 	_Pragma("let " #name " = " #alias)
+
+// GCC has various useful declarations that can be made with the
+//    `__attribute__' syntax.  All of the ways we use this do fine if
+//    they are omitted for compilers that don't understand it.
+
+// At some point during the gcc 2.96 development the `malloc' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+
+// Tell the compiler which arguments to an allocation function
+//    indicate the size of the allocation.
+
+// At some point during the gcc 2.96 development the `pure' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+
+// This declaration tells the compiler that the value is constant.
+
+// At some point during the gcc 3.1 development the `used' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+
+// Since version 3.2, gcc allows marking deprecated functions.
+
+// Since version 4.5, gcc also allows one to specify the message printed
+//    when a deprecated function is used.  clang claims to be gcc 4.2, but
+//    may also support this feature.
+
+// At some point during the gcc 2.8 development the `format_arg' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+//    If several `format_arg' attributes are given for the same function, in
+//    gcc-3.0 and older, all but the last one are ignored.  In newer gccs,
+//    all designated arguments are considered.
+
+// At some point during the gcc 2.97 development the `strfmon' format
+//    attribute for functions was introduced.  We don't want to use it
+//    unconditionally (although this would be possible) since it
+//    generates warnings.
+
+// The nonull function attribute allows to mark pointer parameters which
+//    must not be NULL.
+
+// If fortification mode, we warn about unused results of certain
+//    function calls which can lead to problems.
+
+// Forces a function to be always inlined.
+// The Linux kernel defines __always_inline in stddef.h (283d7573), and
+//    it conflicts with this definition.  Therefore undefine it first to
+//    allow either header to be included first.
+
+// Associate error messages with the source location of the call site rather
+//    than with the source location inside the function.
+
+// GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
+//    inline semantics, unless -fgnu89-inline is used.  Using __GNUC_STDC_INLINE__
+//    or __GNUC_GNU_INLINE is not a good enough check for gcc because gcc versions
+//    older than 4.3 may define these macros and still not guarantee GNU inlining
+//    semantics.
+//
+//    clang++ identifies itself as gcc-4.2, but has support for GNU inlining
+//    semantics, that can be checked for by using the __GNUC_STDC_INLINE_ and
+//    __GNUC_GNU_INLINE__ macro definitions.
+
+// GCC 4.3 and above allow passing all anonymous arguments of an
+//    __extern_always_inline function to some other vararg function.
+
+// It is possible to compile containing GCC extensions even if GCC is
+//    run in pedantic mode if the uses are carefully marked using the
+//    `__extension__' keyword.  But this is not generally available before
+//    version 2.8.
+
+// __restrict is known in EGCS 1.2 and above.

+// The machine-dependent file <bits/typesizes.h> defines __*_T_TYPE
+//    macros for each of the OS types we define below.  The definitions
+//    of those macros must use the following macros for underlying types.
+//    We define __S<SIZE>_TYPE and __U<SIZE>_TYPE for the signed and unsigned
+//    variants of each of the following integer types on this machine.
+//
+// 	16		-- "natural" 16-bit type (always short)
+// 	32		-- "natural" 32-bit type (always int)
+// 	64		-- "natural" 64-bit type (long or long long)
+// 	LONG32		-- 32-bit type, traditionally long
+// 	QUAD		-- 64-bit type, traditionally long long
+// 	WORD		-- natural type of __WORDSIZE bits (int or long)
+// 	LONGWORD	-- type of __WORDSIZE bits, traditionally long
+//
+//    We distinguish WORD/LONGWORD, 32/LONG32, and 64/QUAD so that the
+//    conventional uses of `long' or `long long' type modifiers match the
+//    types we define, even when a less-adorned type would be the same size.
+//    This matters for (somewhat) portably writing printf/scanf formats for
+//    these types, where using the appropriate l or ll format modifiers can
+//    make the typedefs and the formats match up across all GNU platforms.  If
+//    we used `long' when it's 64 bits where `long long' is expected, then the
+//    compiler would warn about the formats not matching the argument types,
+//    and the programmer changing them to shut up the compiler would break the
+//    program's portability.
+//
+//    Here we assume what is presently the case in all the GCC configurations
+//    we support: long long is always 64 bits, long is always word/address size,
+//    and int is always 32 bits.
+
+// We want __extension__ before typedef's that use nonstandard base types
+//    such as `long long' in C89 mode.

+//    The `-ansi' switch to the GNU C compiler, and standards conformance

+//
+//    These are defined by this file and are used by the
+//    header files to decide what to declare or define:
+//
+//    __GLIBC_USE (F)	Define things from feature set F.  This is defined

+//    __USE_ISOCXX11	Define ISO C++11 things.
+//    __USE_POSIX		Define IEEE Std 1003.1 things.
+//    __USE_POSIX2		Define IEEE Std 1003.2 things.
+//    __USE_POSIX199309	Define IEEE Std 1003.1, and .1b things.

+//    __USE_FILE_OFFSET64	Define 64bit interface as default.
+//    __USE_MISC		Define things from 4.3BSD or System V Unix.
+//    __USE_ATFILE		Define *at interfaces and AT_* constants for them.
+//    __USE_GNU		Define GNU extensions.
+//    __USE_FORTIFY_LEVEL	Additional security measures used, according to level.
+//
+//    The macros `__GNU_LIBRARY__', `__GLIBC__', and `__GLIBC_MINOR__' are
+//    defined by this file unconditionally.  `__GNU_LIBRARY__' is provided
+//    only for compatibility.  All new code should use the other symbols
+//    to test for features.
+//
+//    All macros listed above as possibly being defined by this file are
+//    explicitly undefined if they are not explicitly defined.
+//    Feature-test macros that are not defined by the user or compiler
+//    but are implied by the other feature-test macros defined (or by the
+//    lack of any definitions) are defined by the file.
+//
+//    ISO C feature test macros depend on the definition of the macro
+//    when an affected header is included, not when the first system
+//    header is included, and so they are handled in
+//    <bits/libc-header-start.h>, which does not have a multiple include
+//    guard.  Feature test macros that can be handled from the first
+//    system header included are handled here.
+
+// Undefine everything, so we get a clean slate.
+
+// Suppress kernel-name space pollution unless user expressedly asks
+//    for it.
+
+// Convenience macro to test the version of gcc.
+//    Use like this:
+//    #if __GNUC_PREREQ (2,8)
+//    ... code requiring gcc 2.8 or later ...
+//    #endif
+//    Note: only works for GCC 2.0 and later, because __GNUC_MINOR__ was
+//    added in 2.0.
+
+// Similarly for clang.  Features added to GCC after version 4.2 may
+//    or may not also be available in clang, and clang's definitions of
+//    __GNUC(_MINOR)__ are fixed at 4 and 2 respectively.  Not all such
+//    features can be queried via __has_extension/__has_feature.
+
+// Whether to use feature set F.
+
+// _BSD_SOURCE and _SVID_SOURCE are deprecated aliases for
+//    _DEFAULT_SOURCE.  If _DEFAULT_SOURCE is present we do not
+//    issue a warning; the expectation is that the source is being
+//    transitioned to use the new macro.
+
+// If _GNU_SOURCE was defined by the user, turn on all the other features.
+
+// If nothing (other than _GNU_SOURCE and _DEFAULT_SOURCE) is defined,
+//    define _DEFAULT_SOURCE.
+
+// This is to enable the ISO C2X extension.
+
+// This is to enable the ISO C11 extension.
+
+// This is to enable the ISO C99 extension.
+
+// This is to enable the ISO C90 Amendment 1:1995 extension.
+
+// If none of the ANSI/POSIX macros are defined, or if _DEFAULT_SOURCE
+//    is defined, use POSIX.1-2008 (or another version depending on
+//    _XOPEN_SOURCE).
+
+// Some C libraries once required _REENTRANT and/or _THREAD_SAFE to be
+//    defined in all multithreaded code.  GNU libc has not required this
+//    for many years.  We now treat them as compatibility synonyms for
+//    _POSIX_C_SOURCE=199506L, which is the earliest level of POSIX with
+//    comprehensive support for multithreaded code.  Using them never
+//    lowers the selected level of POSIX conformance, only raises it.
+
+// The function 'gets' existed in C89, but is impossible to use
+//    safely.  It has been removed from ISO C11 and ISO C++14.  Note: for
+//    compatibility with various implementations of <cstdio>, this test
+//    must consider only the value of __cplusplus when compiling C++.
+
+// GNU formerly extended the scanf functions with modified format
+//    specifiers %as, %aS, and %a[...] that allocate a buffer for the
+//    input using malloc.  This extension conflicts with ISO C99, which
+//    defines %a as a standalone format specifier that reads a floating-
+//    point number; moreover, POSIX.1-2008 provides the same feature
+//    using the modifier letter 'm' instead (%ms, %mS, %m[...]).
+//
+//    We now follow C99 unless GNU extensions are active and the compiler
+//    is specifically in C89 or C++98 mode (strict or not).  For
+//    instance, with GCC, -std=gnu11 will have C99-compliant scanf with
+//    or without -D_GNU_SOURCE, but -std=c89 -D_GNU_SOURCE will have the
+//    old extension.

+// The GNU libc does not support any K&R compilers or the traditional mode

+
+// Some user header file might have defined this before.
+
+// All functions, except those with callbacks or those that
+//    synchronize memory, are leaf functions.
+
+// GCC can always grok prototypes.  For C++ programs we add throw()
+//    to help it optimize the function calls.  But this works only with
+//    gcc 2.8.x and egcs.  For gcc 3.2 and up we even mark C functions
+//    as non-throwing using a function attribute since programs can use
+//    the -fexceptions options for C code as well.
+
+// Compilers that are not clang may object to
+//        #if defined __clang__ && __has_extension(...)
+//    even though they do not need to evaluate the right-hand side of the &&.
+
+// These two macros are not used in glibc anymore.  They are kept here
+//    only because some other projects expect the macros to be defined.
+
+// For these things, GCC behaves the ANSI way normally,
+//    and the non-ANSI way under -traditional.
+
+// This is not a typedef so `const __ptr_t' does the right thing.
+
+// C++ needs to know that types and declarations are C, not C++.
+
+// Fortify support.
+
+// Support for flexible arrays.
+//    Headers that should use flexible arrays only if they're "real"
+//    (e.g. only if they won't affect sizeof()) should test
+//    #if __glibc_c99_flexarr_available.
+
+// __asm__ ("xyz") is used throughout the headers to rename functions
+//    at the assembly language level.  This is wrapped by the __REDIRECT
+//    macro, in order to support compilers that can do this some other
+//    way.  When compilers don't support asm-names at all, we have to do
+//    preprocessor tricks instead (which don't have exactly the right
+//    semantics, but it's the best we can do).
+//
+//    Example:
+//    int __REDIRECT(setpgrp, (__pid_t pid, __pid_t pgrp), setpgid);
+
+//
+// #elif __SOME_OTHER_COMPILER__
+//
+// # define __REDIRECT(name, proto, alias) name proto; 	_Pragma("let " #name " = " #alias)
+
+// GCC has various useful declarations that can be made with the
+//    `__attribute__' syntax.  All of the ways we use this do fine if
+//    they are omitted for compilers that don't understand it.
+
+// At some point during the gcc 2.96 development the `malloc' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+
+// Tell the compiler which arguments to an allocation function
+//    indicate the size of the allocation.
+
+// At some point during the gcc 2.96 development the `pure' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+
+// This declaration tells the compiler that the value is constant.
+
+// At some point during the gcc 3.1 development the `used' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+
+// Since version 3.2, gcc allows marking deprecated functions.
+
+// Since version 4.5, gcc also allows one to specify the message printed
+//    when a deprecated function is used.  clang claims to be gcc 4.2, but
+//    may also support this feature.
+
+// At some point during the gcc 2.8 development the `format_arg' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+//    If several `format_arg' attributes are given for the same function, in
+//    gcc-3.0 and older, all but the last one are ignored.  In newer gccs,
+//    all designated arguments are considered.
+
+// At some point during the gcc 2.97 development the `strfmon' format
+//    attribute for functions was introduced.  We don't want to use it
+//    unconditionally (although this would be possible) since it
+//    generates warnings.
+
+// The nonull function attribute allows to mark pointer parameters which
+//    must not be NULL.
+
+// If fortification mode, we warn about unused results of certain
+//    function calls which can lead to problems.
+
+// Forces a function to be always inlined.
+// The Linux kernel defines __always_inline in stddef.h (283d7573), and
+//    it conflicts with this definition.  Therefore undefine it first to
+//    allow either header to be included first.
+
+// Associate error messages with the source location of the call site rather
+//    than with the source location inside the function.
+
+// GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
+//    inline semantics, unless -fgnu89-inline is used.  Using __GNUC_STDC_INLINE__
+//    or __GNUC_GNU_INLINE is not a good enough check for gcc because gcc versions
+//    older than 4.3 may define these macros and still not guarantee GNU inlining
+//    semantics.
+//
+//    clang++ identifies itself as gcc-4.2, but has support for GNU inlining
+//    semantics, that can be checked for by using the __GNUC_STDC_INLINE_ and
+//    __GNUC_GNU_INLINE__ macro definitions.
+
+// GCC 4.3 and above allow passing all anonymous arguments of an
+//    __extern_always_inline function to some other vararg function.
+
+// It is possible to compile containing GCC extensions even if GCC is
+//    run in pedantic mode if the uses are carefully marked using the
+//    `__extension__' keyword.  But this is not generally available before

+
+// __restrict is known in EGCS 1.2 and above.

+// The machine-dependent file <bits/typesizes.h> defines __*_T_TYPE

+//    of those macros must use the following macros for underlying types.
+//    We define __S<SIZE>_TYPE and __U<SIZE>_TYPE for the signed and unsigned
+//    variants of each of the following integer types on this machine.
+//
+// 	16		-- "natural" 16-bit type (always short)
+// 	32		-- "natural" 32-bit type (always int)
+// 	64		-- "natural" 64-bit type (long or long long)
+// 	LONG32		-- 32-bit type, traditionally long
+// 	QUAD		-- 64-bit type, traditionally long long
+// 	WORD		-- natural type of __WORDSIZE bits (int or long)
+// 	LONGWORD	-- type of __WORDSIZE bits, traditionally long
+//
+//    We distinguish WORD/LONGWORD, 32/LONG32, and 64/QUAD so that the
+//    conventional uses of `long' or `long long' type modifiers match the
+//    types we define, even when a less-adorned type would be the same size.
+//    This matters for (somewhat) portably writing printf/scanf formats for
+//    these types, where using the appropriate l or ll format modifiers can
+//    make the typedefs and the formats match up across all GNU platforms.  If
+//    we used `long' when it's 64 bits where `long long' is expected, then the
+//    compiler would warn about the formats not matching the argument types,
+//    and the programmer changing them to shut up the compiler would break the
+//    program's portability.
+//
+//    Here we assume what is presently the case in all the GCC configurations
+//    we support: long long is always 64 bits, long is always word/address size,
+//    and int is always 32 bits.
+
+// No need to mark the typedef with __extension__.

+//
+//    These are defined by this file and are used by the

+//
+//    __GLIBC_USE (F)	Define things from feature set F.  This is defined

+//    __USE_POSIX199309	Define IEEE Std 1003.1, and .1b things.

+//    __USE_FILE_OFFSET64	Define 64bit interface as default.
+//    __USE_MISC		Define things from 4.3BSD or System V Unix.
+//    __USE_ATFILE		Define *at interfaces and AT_* constants for them.
+//    __USE_GNU		Define GNU extensions.
+//    __USE_FORTIFY_LEVEL	Additional security measures used, according to level.
+//
+//    The macros `__GNU_LIBRARY__', `__GLIBC__', and `__GLIBC_MINOR__' are
+//    defined by this file unconditionally.  `__GNU_LIBRARY__' is provided
+//    only for compatibility.  All new code should use the other symbols
+//    to test for features.
+//
+//    All macros listed above as possibly being defined by this file are
+//    explicitly undefined if they are not explicitly defined.
+//    Feature-test macros that are not defined by the user or compiler
+//    but are implied by the other feature-test macros defined (or by the
+//    lack of any definitions) are defined by the file.
+//
+//    ISO C feature test macros depend on the definition of the macro
+//    when an affected header is included, not when the first system
+//    header is included, and so they are handled in
+//    <bits/libc-header-start.h>, which does not have a multiple include
+//    guard.  Feature test macros that can be handled from the first
+//    system header included are handled here.
+
+// Undefine everything, so we get a clean slate.
+
+// Suppress kernel-name space pollution unless user expressedly asks
+//    for it.
+
+// Convenience macro to test the version of gcc.
+//    Use like this:
+//    #if __GNUC_PREREQ (2,8)
+//    ... code requiring gcc 2.8 or later ...
+//    #endif
+//    Note: only works for GCC 2.0 and later, because __GNUC_MINOR__ was
+//    added in 2.0.
+
+// Similarly for clang.  Features added to GCC after version 4.2 may
+//    or may not also be available in clang, and clang's definitions of
+//    __GNUC(_MINOR)__ are fixed at 4 and 2 respectively.  Not all such
+//    features can be queried via __has_extension/__has_feature.
+
+// Whether to use feature set F.
+
+// _BSD_SOURCE and _SVID_SOURCE are deprecated aliases for
+//    _DEFAULT_SOURCE.  If _DEFAULT_SOURCE is present we do not
+//    issue a warning; the expectation is that the source is being
+//    transitioned to use the new macro.
+
+// If _GNU_SOURCE was defined by the user, turn on all the other features.
+
+// If nothing (other than _GNU_SOURCE and _DEFAULT_SOURCE) is defined,
+//    define _DEFAULT_SOURCE.
+
+// This is to enable the ISO C2X extension.
+
+// This is to enable the ISO C11 extension.
+
+// This is to enable the ISO C99 extension.
+
+// This is to enable the ISO C90 Amendment 1:1995 extension.
+
+// If none of the ANSI/POSIX macros are defined, or if _DEFAULT_SOURCE
+//    is defined, use POSIX.1-2008 (or another version depending on
+//    _XOPEN_SOURCE).
+
+// Some C libraries once required _REENTRANT and/or _THREAD_SAFE to be
+//    defined in all multithreaded code.  GNU libc has not required this
+//    for many years.  We now treat them as compatibility synonyms for
+//    _POSIX_C_SOURCE=199506L, which is the earliest level of POSIX with
+//    comprehensive support for multithreaded code.  Using them never
+//    lowers the selected level of POSIX conformance, only raises it.
+
+// The function 'gets' existed in C89, but is impossible to use
+//    safely.  It has been removed from ISO C11 and ISO C++14.  Note: for
+//    compatibility with various implementations of <cstdio>, this test
+//    must consider only the value of __cplusplus when compiling C++.
+
+// GNU formerly extended the scanf functions with modified format
+//    specifiers %as, %aS, and %a[...] that allocate a buffer for the
+//    input using malloc.  This extension conflicts with ISO C99, which
+//    defines %a as a standalone format specifier that reads a floating-
+//    point number; moreover, POSIX.1-2008 provides the same feature
+//    using the modifier letter 'm' instead (%ms, %mS, %m[...]).
+//
+//    We now follow C99 unless GNU extensions are active and the compiler
+//    is specifically in C89 or C++98 mode (strict or not).  For
+//    instance, with GCC, -std=gnu11 will have C99-compliant scanf with
+//    or without -D_GNU_SOURCE, but -std=c89 -D_GNU_SOURCE will have the
+//    old extension.

+// The GNU libc does not support any K&R compilers or the traditional mode

+
+// Some user header file might have defined this before.
+
+// All functions, except those with callbacks or those that
+//    synchronize memory, are leaf functions.
+
+// GCC can always grok prototypes.  For C++ programs we add throw()
+//    to help it optimize the function calls.  But this works only with
+//    gcc 2.8.x and egcs.  For gcc 3.2 and up we even mark C functions
+//    as non-throwing using a function attribute since programs can use
+//    the -fexceptions options for C code as well.
+
+// Compilers that are not clang may object to
+//        #if defined __clang__ && __has_extension(...)
+//    even though they do not need to evaluate the right-hand side of the &&.
+
+// These two macros are not used in glibc anymore.  They are kept here
+//    only because some other projects expect the macros to be defined.
+
+// For these things, GCC behaves the ANSI way normally,
+//    and the non-ANSI way under -traditional.
+
+// This is not a typedef so `const __ptr_t' does the right thing.
+
+// C++ needs to know that types and declarations are C, not C++.
+
+// Fortify support.
+
+// Support for flexible arrays.
+//    Headers that should use flexible arrays only if they're "real"
+//    (e.g. only if they won't affect sizeof()) should test
+//    #if __glibc_c99_flexarr_available.
+
+// __asm__ ("xyz") is used throughout the headers to rename functions
+//    at the assembly language level.  This is wrapped by the __REDIRECT
+//    macro, in order to support compilers that can do this some other
+//    way.  When compilers don't support asm-names at all, we have to do
+//    preprocessor tricks instead (which don't have exactly the right
+//    semantics, but it's the best we can do).
+//
+//    Example:
+//    int __REDIRECT(setpgrp, (__pid_t pid, __pid_t pgrp), setpgid);
+
+//
+// #elif __SOME_OTHER_COMPILER__
+//
+// # define __REDIRECT(name, proto, alias) name proto; 	_Pragma("let " #name " = " #alias)
+
+// GCC has various useful declarations that can be made with the
+//    `__attribute__' syntax.  All of the ways we use this do fine if
+//    they are omitted for compilers that don't understand it.
+
+// At some point during the gcc 2.96 development the `malloc' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+
+// Tell the compiler which arguments to an allocation function
+//    indicate the size of the allocation.
+
+// At some point during the gcc 2.96 development the `pure' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+
+// This declaration tells the compiler that the value is constant.
+
+// At some point during the gcc 3.1 development the `used' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+
+// Since version 3.2, gcc allows marking deprecated functions.
+
+// Since version 4.5, gcc also allows one to specify the message printed
+//    when a deprecated function is used.  clang claims to be gcc 4.2, but
+//    may also support this feature.
+
+// At some point during the gcc 2.8 development the `format_arg' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+//    If several `format_arg' attributes are given for the same function, in
+//    gcc-3.0 and older, all but the last one are ignored.  In newer gccs,
+//    all designated arguments are considered.
+
+// At some point during the gcc 2.97 development the `strfmon' format
+//    attribute for functions was introduced.  We don't want to use it
+//    unconditionally (although this would be possible) since it
+//    generates warnings.
+
+// The nonull function attribute allows to mark pointer parameters which
+//    must not be NULL.
+
+// If fortification mode, we warn about unused results of certain
+//    function calls which can lead to problems.
+
+// Forces a function to be always inlined.
+// The Linux kernel defines __always_inline in stddef.h (283d7573), and
+//    it conflicts with this definition.  Therefore undefine it first to
+//    allow either header to be included first.
+
+// Associate error messages with the source location of the call site rather
+//    than with the source location inside the function.
+
+// GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
+//    inline semantics, unless -fgnu89-inline is used.  Using __GNUC_STDC_INLINE__
+//    or __GNUC_GNU_INLINE is not a good enough check for gcc because gcc versions
+//    older than 4.3 may define these macros and still not guarantee GNU inlining
+//    semantics.
+//
+//    clang++ identifies itself as gcc-4.2, but has support for GNU inlining
+//    semantics, that can be checked for by using the __GNUC_STDC_INLINE_ and
+//    __GNUC_GNU_INLINE__ macro definitions.
+
+// GCC 4.3 and above allow passing all anonymous arguments of an
+//    __extern_always_inline function to some other vararg function.
+
+// It is possible to compile containing GCC extensions even if GCC is
+//    run in pedantic mode if the uses are carefully marked using the
+//    `__extension__' keyword.  But this is not generally available before
+//    version 2.8.
+
+// __restrict is known in EGCS 1.2 and above.
+
+// ISO C99 also allows to declare arrays as non-overlapping.  The syntax is

+// The machine-dependent file <bits/typesizes.h> defines __*_T_TYPE
+//    macros for each of the OS types we define below.  The definitions
+//    of those macros must use the following macros for underlying types.
+//    We define __S<SIZE>_TYPE and __U<SIZE>_TYPE for the signed and unsigned
+//    variants of each of the following integer types on this machine.
+//
+// 	16		-- "natural" 16-bit type (always short)
+// 	32		-- "natural" 32-bit type (always int)
+// 	64		-- "natural" 64-bit type (long or long long)
+// 	LONG32		-- 32-bit type, traditionally long
+// 	QUAD		-- 64-bit type, traditionally long long
+// 	WORD		-- natural type of __WORDSIZE bits (int or long)
+// 	LONGWORD	-- type of __WORDSIZE bits, traditionally long
+//
+//    We distinguish WORD/LONGWORD, 32/LONG32, and 64/QUAD so that the
+//    conventional uses of `long' or `long long' type modifiers match the
+//    types we define, even when a less-adorned type would be the same size.
+//    This matters for (somewhat) portably writing printf/scanf formats for
+//    these types, where using the appropriate l or ll format modifiers can
+//    make the typedefs and the formats match up across all GNU platforms.  If
+//    we used `long' when it's 64 bits where `long long' is expected, then the
+//    compiler would warn about the formats not matching the argument types,
+//    and the programmer changing them to shut up the compiler would break the
+//    program's portability.
+//
+//    Here we assume what is presently the case in all the GCC configurations
+//    we support: long long is always 64 bits, long is always word/address size,
+//    and int is always 32 bits.
+
+// We want __extension__ before typedef's that use nonstandard base types
+//    such as `long long' in C89 mode.

+//    __USE_ATFILE		Define *at interfaces and AT_* constants for them.
+//    __USE_GNU		Define GNU extensions.
+//    __USE_FORTIFY_LEVEL	Additional security measures used, according to level.
+//
+//    The macros `__GNU_LIBRARY__', `__GLIBC__', and `__GLIBC_MINOR__' are
+//    defined by this file unconditionally.  `__GNU_LIBRARY__' is provided
+//    only for compatibility.  All new code should use the other symbols
+//    to test for features.
+//
+//    All macros listed above as possibly being defined by this file are
+//    explicitly undefined if they are not explicitly defined.
+//    Feature-test macros that are not defined by the user or compiler
+//    but are implied by the other feature-test macros defined (or by the
+//    lack of any definitions) are defined by the file.
+//
+//    ISO C feature test macros depend on the definition of the macro
+//    when an affected header is included, not when the first system
+//    header is included, and so they are handled in
+//    <bits/libc-header-start.h>, which does not have a multiple include
+//    guard.  Feature test macros that can be handled from the first
+//    system header included are handled here.
+
+// Undefine everything, so we get a clean slate.
+
+// Suppress kernel-name space pollution unless user expressedly asks
+//    for it.
+
+// Convenience macro to test the version of gcc.
+//    Use like this:
+//    #if __GNUC_PREREQ (2,8)
+//    ... code requiring gcc 2.8 or later ...
+//    #endif
+//    Note: only works for GCC 2.0 and later, because __GNUC_MINOR__ was
+//    added in 2.0.
+
+// Similarly for clang.  Features added to GCC after version 4.2 may
+//    or may not also be available in clang, and clang's definitions of
+//    __GNUC(_MINOR)__ are fixed at 4 and 2 respectively.  Not all such
+//    features can be queried via __has_extension/__has_feature.
+
+// Whether to use feature set F.
+
+// _BSD_SOURCE and _SVID_SOURCE are deprecated aliases for
+//    _DEFAULT_SOURCE.  If _DEFAULT_SOURCE is present we do not
+//    issue a warning; the expectation is that the source is being
+//    transitioned to use the new macro.
+
+// If _GNU_SOURCE was defined by the user, turn on all the other features.
+
+// If nothing (other than _GNU_SOURCE and _DEFAULT_SOURCE) is defined,
+//    define _DEFAULT_SOURCE.
+
+// This is to enable the ISO C2X extension.
+
+// This is to enable the ISO C11 extension.
+
+// This is to enable the ISO C99 extension.
+
+// This is to enable the ISO C90 Amendment 1:1995 extension.
+
+// If none of the ANSI/POSIX macros are defined, or if _DEFAULT_SOURCE
+//    is defined, use POSIX.1-2008 (or another version depending on
+//    _XOPEN_SOURCE).
+
+// Some C libraries once required _REENTRANT and/or _THREAD_SAFE to be
+//    defined in all multithreaded code.  GNU libc has not required this
+//    for many years.  We now treat them as compatibility synonyms for
+//    _POSIX_C_SOURCE=199506L, which is the earliest level of POSIX with
+//    comprehensive support for multithreaded code.  Using them never
+//    lowers the selected level of POSIX conformance, only raises it.
+
+// The function 'gets' existed in C89, but is impossible to use
+//    safely.  It has been removed from ISO C11 and ISO C++14.  Note: for
+//    compatibility with various implementations of <cstdio>, this test
+//    must consider only the value of __cplusplus when compiling C++.
+
+// GNU formerly extended the scanf functions with modified format
+//    specifiers %as, %aS, and %a[...] that allocate a buffer for the
+//    input using malloc.  This extension conflicts with ISO C99, which
+//    defines %a as a standalone format specifier that reads a floating-
+//    point number; moreover, POSIX.1-2008 provides the same feature
+//    using the modifier letter 'm' instead (%ms, %mS, %m[...]).
+//
+//    We now follow C99 unless GNU extensions are active and the compiler
+//    is specifically in C89 or C++98 mode (strict or not).  For
+//    instance, with GCC, -std=gnu11 will have C99-compliant scanf with
+//    or without -D_GNU_SOURCE, but -std=c89 -D_GNU_SOURCE will have the
+//    old extension.

+
+// Some user header file might have defined this before.
+
+// All functions, except those with callbacks or those that
+//    synchronize memory, are leaf functions.
+
+// GCC can always grok prototypes.  For C++ programs we add throw()
+//    to help it optimize the function calls.  But this works only with
+//    gcc 2.8.x and egcs.  For gcc 3.2 and up we even mark C functions
+//    as non-throwing using a function attribute since programs can use
+//    the -fexceptions options for C code as well.
+
+// Compilers that are not clang may object to
+//        #if defined __clang__ && __has_extension(...)
+//    even though they do not need to evaluate the right-hand side of the &&.
+
+// These two macros are not used in glibc anymore.  They are kept here
+//    only because some other projects expect the macros to be defined.
+
+// For these things, GCC behaves the ANSI way normally,
+//    and the non-ANSI way under -traditional.
+
+// This is not a typedef so `const __ptr_t' does the right thing.
+
+// C++ needs to know that types and declarations are C, not C++.
+
+// Fortify support.
+
+// Support for flexible arrays.
+//    Headers that should use flexible arrays only if they're "real"
+//    (e.g. only if they won't affect sizeof()) should test
+//    #if __glibc_c99_flexarr_available.
+
+// __asm__ ("xyz") is used throughout the headers to rename functions
+//    at the assembly language level.  This is wrapped by the __REDIRECT
+//    macro, in order to support compilers that can do this some other
+//    way.  When compilers don't support asm-names at all, we have to do
+//    preprocessor tricks instead (which don't have exactly the right
+//    semantics, but it's the best we can do).
+//
+//    Example:
+//    int __REDIRECT(setpgrp, (__pid_t pid, __pid_t pgrp), setpgid);
+
+//
+// #elif __SOME_OTHER_COMPILER__
+//
+// # define __REDIRECT(name, proto, alias) name proto; 	_Pragma("let " #name " = " #alias)
+
+// GCC has various useful declarations that can be made with the
+//    `__attribute__' syntax.  All of the ways we use this do fine if
+//    they are omitted for compilers that don't understand it.
+
+// At some point during the gcc 2.96 development the `malloc' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+
+// Tell the compiler which arguments to an allocation function
+//    indicate the size of the allocation.
+
+// At some point during the gcc 2.96 development the `pure' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+
+// This declaration tells the compiler that the value is constant.
+
+// At some point during the gcc 3.1 development the `used' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+
+// Since version 3.2, gcc allows marking deprecated functions.
+
+// Since version 4.5, gcc also allows one to specify the message printed
+//    when a deprecated function is used.  clang claims to be gcc 4.2, but
+//    may also support this feature.
+
+// At some point during the gcc 2.8 development the `format_arg' attribute
+//    for functions was introduced.  We don't want to use it unconditionally
+//    (although this would be possible) since it generates warnings.
+//    If several `format_arg' attributes are given for the same function, in
+//    gcc-3.0 and older, all but the last one are ignored.  In newer gccs,
+//    all designated arguments are considered.
+
+// At some point during the gcc 2.97 development the `strfmon' format
+//    attribute for functions was introduced.  We don't want to use it
+//    unconditionally (although this would be possible) since it
+//    generates warnings.
+
+// The nonull function attribute allows to mark pointer parameters which
+//    must not be NULL.
+
+// If fortification mode, we warn about unused results of certain
+//    function calls which can lead to problems.
+
+// Forces a function to be always inlined.
+// The Linux kernel defines __always_inline in stddef.h (283d7573), and
+//    it conflicts with this definition.  Therefore undefine it first to
+//    allow either header to be included first.
+
+// Associate error messages with the source location of the call site rather
+//    than with the source location inside the function.
+
+// GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
+//    inline semantics, unless -fgnu89-inline is used.  Using __GNUC_STDC_INLINE__
+//    or __GNUC_GNU_INLINE is not a good enough check for gcc because gcc versions
+//    older than 4.3 may define these macros and still not guarantee GNU inlining
+//    semantics.
+//
+//    clang++ identifies itself as gcc-4.2, but has support for GNU inlining
+//    semantics, that can be checked for by using the __GNUC_STDC_INLINE_ and
+//    __GNUC_GNU_INLINE__ macro definitions.
+
+// GCC 4.3 and above allow passing all anonymous arguments of an
+//    __extern_always_inline function to some other vararg function.
+
+// It is possible to compile containing GCC extensions even if GCC is
+//    run in pedantic mode if the uses are carefully marked using the
+//    `__extension__' keyword.  But this is not generally available before
+//    version 2.8.
+
+// __restrict is known in EGCS 1.2 and above.
+
+// ISO C99 also allows to declare arrays as non-overlapping.  The syntax is

+//    We define __S<SIZE>_TYPE and __U<SIZE>_TYPE for the signed and unsigned
+//    variants of each of the following integer types on this machine.
+//
+// 	16		-- "natural" 16-bit type (always short)
+// 	32		-- "natural" 32-bit type (always int)
+// 	64		-- "natural" 64-bit type (long or long long)
+// 	LONG32		-- 32-bit type, traditionally long
+// 	QUAD		-- 64-bit type, traditionally long long
+// 	WORD		-- natural type of __WORDSIZE bits (int or long)
+// 	LONGWORD	-- type of __WORDSIZE bits, traditionally long
+//
+//    We distinguish WORD/LONGWORD, 32/LONG32, and 64/QUAD so that the
+//    conventional uses of `long' or `long long' type modifiers match the
+//    types we define, even when a less-adorned type would be the same size.
+//    This matters for (somewhat) portably writing printf/scanf formats for
+//    these types, where using the appropriate l or ll format modifiers can
+//    make the typedefs and the formats match up across all GNU platforms.  If
+//    we used `long' when it's 64 bits where `long long' is expected, then the
+//    compiler would warn about the formats not matching the argument types,
+//    and the programmer changing them to shut up the compiler would break the
+//    program's portability.
+//
+//    Here we assume what is presently the case in all the GCC configurations
+//    we support: long long is always 64 bits, long is always word/address size,
+//    and int is always 32 bits.

+//    __USE_ATFILE		Define *at interfaces and AT_* constants for them.
+//    __USE_GNU		Define GNU extensions.

+//    The macros `__GNU_LIBRARY__', `__GLIBC__', and `__GLIBC_MINOR__' are
+//    defined by this file unconditionally.  `__GNU_LIBRARY__' is provided
+//    only for compatibility.  All new code should use the other symbols
+//    to test for features.
+//
+//    All macros listed above as possibly being defined by this file are
+//    explicitly undefined if they are not explicitly defined.
+//    Feature-test macros that are not defined by the user or compiler
+//    but are implied by the other feature-test macros defined (or by the
+//    lack of any definitions) are defined by the file.
+//
+//    ISO C feature test macros depend on the definition of the macro
+//    when an affected header is included, not when the first system
+//    header is included, and so they are handled in
+//    <bits/libc-header-start.h>, which does not have a multiple include
+//    guard.  Feature test macros that can be handled from the first
+//    system header included are handled here.
+
+// Undefine everything, so we get a clean slate.
+
+// Suppress kernel-name space pollution unless user expressedly asks
+//    for it.
+
+// Convenience macro to test the version of gcc.
+//    Use like this:
+//    #if __GNUC_PREREQ (2,8)
+//    ... code requiring gcc 2.8 or later ...
+//    #endif
+//    Note: only works for GCC 2.0 and later, because __GNUC_MINOR__ was
+//    added in 2.0.
+
+// Similarly for clang.  Features added to GCC after version 4.2 may
+//    or may not also be available in clang, and clang's definitions of
+//    __GNUC(_MINOR)__ are fixed at 4 and 2 respectively.  Not all such
+//    features can be queried via __has_extension/__has_feature.
+
+// Whether to use feature set F.
+
+// _BSD_SOURCE and _SVID_SOURCE are deprecated aliases for
+//    _DEFAULT_SOURCE.  If _DEFAULT_SOURCE is present we do not
+//    issue a warning; the expectation is that the source is being
+//    transitioned to use the new macro.
+
+// If _GNU_SOURCE was defined by the user, turn on all the other features.
+
+// If nothing (other than _GNU_SOURCE and _DEFAULT_SOURCE) is defined,
+//    define _DEFAULT_SOURCE.
+
+// This is to enable the ISO C2X extension.
+
+// This is to enable the ISO C11 extension.
+
+// This is to enable the ISO C99 extension.
+
+// This is to enable the ISO C90 Amendment 1:1995 extension.
+
+// If none of the ANSI/POSIX macros are defined, or if _DEFAULT_SOURCE
+//    is defined, use POSIX.1-2008 (or another version depending on
+//    _XOPEN_SOURCE).
+
+// Some C libraries once required _REENTRANT and/or _THREAD_SAFE to be
+//    defined in all multithreaded code.  GNU libc has not required this
+//    for many years.  We now treat them as compatibility synonyms for
+//    _POSIX_C_SOURCE=199506L, which is the earliest level of POSIX with
+//    comprehensive support for multithreaded code.  Using them never
+//    lowers the selected level of POSIX conformance, only raises it.
+
+// The function 'gets' existed in C89, but is impossible to use
+//    safely.  It has been removed from ISO C11 and ISO C++14.  Note: for
+//    compatibility with various implementations of <cstdio>, this test
+//    must consider only the value of __cplusplus when compiling C++.
+
+// GNU formerly extended the scanf functions with modified format
+//    specifiers %as, %aS, and %a[...] that allocate a buffer for the
+//    input using malloc.  This extension conflicts with ISO C99, which
+//    defines %a as a standalone format specifier that reads a floating-
+//    point number; moreover, POSIX.1-2008 provides the same feature
+//    using the modifier letter 'm' instead (%ms, %mS, %m[...]).
+//
+//    We now follow C99 unless GNU extensions are active and the compiler
+//    is specifically in C89 or C++98 mode (strict or not).  For
+//    instance, with GCC, -std=gnu11 will have C99-compliant scanf with
+//    or without -D_GNU_SOURCE, but -std=c89 -D_GNU_SOURCE will have the
+//    old extension.

+// GCC can always grok prototypes.  For C++ programs we add throw()
+//    to help it optimize the function calls.  But this works only with
+//    gcc 2.8.x and egcs.  For gcc 3.2 and up we even mark C functions
+//    as non-throwing using a function attribute since programs can use

+

+
+// __asm__ ("xyz") is used throughout the headers to rename functions
+//    at the assembly language level.  This is wrapped by the __REDIRECT
+//    macro, in order to support compilers that can do this some other
+//    way.  When compilers don't support asm-names at all, we have to do
+//    preprocessor tricks instead (which don't have exactly the right
+//    semantics, but it's the best we can do).
+//
+//    Example:
+//    int __REDIRECT(setpgrp, (__pid_t pid, __pid_t pgrp), setpgid);
+
+//
+// #elif __SOME_OTHER_COMPILER__
+//
+// # define __REDIRECT(name, proto, alias) name proto; 	_Pragma("let " #name " = " #alias)
+
+// GCC has various useful declarations that can be made with the
+//    `__attribute__' syntax.  All of the ways we use this do fine if

+//    This matters for (somewhat) portably writing printf/scanf formats for
+//    these types, where using the appropriate l or ll format modifiers can
+//    make the typedefs and the formats match up across all GNU platforms.  If
+//    we used `long' when it's 64 bits where `long long' is expected, then the
+//    compiler would warn about the formats not matching the argument types,
+//    and the programmer changing them to shut up the compiler would break the
+//    program's portability.
+//
+//    Here we assume what is presently the case in all the GCC configurations
+//    we support: long long is always 64 bits, long is always word/address size,
+//    and int is always 32 bits.

+// Public domain.
+//
+// NOTE: Do not protect this header against multiple inclusion.  Doing
+// so can have subtle side-effects due to header file inclusion order
+// and testing of e.g. _POSIX_SOURCE vs. _POSIX_C_SOURCE.  Instead,
+// protect each CPP macro that we want to supply.
+
+// Feature-test macros are defined by several standards, and allow an
+// application to specify what symbols they want the system headers to
+// expose, and hence what standard they want them to conform to.
+// There are two classes of feature-test macros.  The first class
+// specify complete standards, and if one of these is defined, header
+// files will try to conform to the relevant standard.  They are:
+//
+// ANSI macros:
+// _ANSI_SOURCE			ANSI C89
+//
+// POSIX macros:
+// _POSIX_SOURCE == 1		IEEE Std 1003.1 (version?)
+// _POSIX_C_SOURCE == 1		IEEE Std 1003.1-1990
+// _POSIX_C_SOURCE == 2		IEEE Std 1003.2-1992
+// _POSIX_C_SOURCE == 199309L	IEEE Std 1003.1b-1993
+// _POSIX_C_SOURCE == 199506L	ISO/IEC 9945-1:1996
+// _POSIX_C_SOURCE == 200112L	IEEE Std 1003.1-2001
+// _POSIX_C_SOURCE == 200809L   IEEE Std 1003.1-2008
+//
+// X/Open macros:
+// _XOPEN_SOURCE		System Interfaces and Headers, Issue 4, Ver 2
+// _XOPEN_SOURCE_EXTENDED == 1	XSH4.2 UNIX extensions
+// _XOPEN_SOURCE == 500		System Interfaces and Headers, Issue 5
+// _XOPEN_SOURCE == 520		Networking Services (XNS), Issue 5.2
+// _XOPEN_SOURCE == 600		IEEE Std 1003.1-2001, XSI option
+// _XOPEN_SOURCE == 700		IEEE Std 1003.1-2008, XSI option
+//
+// NetBSD macros:
+// _NETBSD_SOURCE == 1		Make all NetBSD features available.
+//
+// If more than one of these "major" feature-test macros is defined,
+// then the set of facilities provided (and namespace used) is the
+// union of that specified by the relevant standards, and in case of
+// conflict, the earlier standard in the above list has precedence (so
+// if both _POSIX_C_SOURCE and _NETBSD_SOURCE are defined, the version
+// of rename() that's used is the POSIX one).  If none of the "major"
+// feature-test macros is defined, _NETBSD_SOURCE is assumed.
+//
+// There are also "minor" feature-test macros, which enable extra
+// functionality in addition to some base standard.  They should be
+// defined along with one of the "major" macros.  The "minor" macros
+// are:
+//
+// _REENTRANT
+// _ISOC99_SOURCE
+// _ISOC11_SOURCE
+// _LARGEFILE_SOURCE		Large File Support
+//		<http://ftp.sas.com/standards/large.file/x_open.20Mar96.html>

+// mingw.org's version macros: these make gcc to define
+//    MINGW32_SUPPORTS_MT_EH and to use the _CRT_MT global
+//    and the __mingwthr_key_dtor() function from the MinGW
+//    CRT in its private gthr-win32.h header.

+// MS does not prefix symbols by underscores for 64-bit.
+// As we have to support older gcc version, which are using underscores
+//       as symbol prefix for x64, we have to check here for the user label
+//       prefix defined by gcc.
+
+// Special case nameless struct/union.
+
+// MinGW-w64 has some additional C99 printf/scanf feature support.
+//    So we add some helper macros to ease recognition of them.
