+
+// 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.

+// __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

+// Compiler-dependent macros that bracket portions of code where the

+
+// 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

+
+// 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

+// 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.

+//  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 `-ansi' switch to the GNU C compiler, and standards conformance
+//    options such as `-std=c99', define __STRICT_ANSI__.  If none of
+//    these are defined, or if _DEFAULT_SOURCE is defined, the default is
+//    to have _POSIX_SOURCE set to one and _POSIX_C_SOURCE set to
+//    200809L, as well as enabling miscellaneous functions from BSD and
+//    SVID.  If more than one of these are defined, they accumulate.  For
+//    example __STRICT_ANSI__, _POSIX_SOURCE and _POSIX_C_SOURCE together
+//    give you ISO C, 1003.1, and 1003.2, but nothing else.
+//
+//    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
+// 			__GLIBC_USE.
+//    __USE_ISOC11		Define ISO C11 things.
+//    __USE_ISOC99		Define ISO C99 things.
+//    __USE_ISOC95		Define ISO C90 AMD1 (C95) things.
+//    __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_POSIX199506	Define IEEE Std 1003.1, .1b, .1c and .1i things.
+//    __USE_XOPEN		Define XPG things.
+//    __USE_XOPEN_EXTENDED	Define X/Open Unix things.
+//    __USE_UNIX98		Define Single Unix V2 things.
+//    __USE_XOPEN2K        Define XPG6 things.
+//    __USE_XOPEN2KXSI     Define XPG6 XSI things.
+//    __USE_XOPEN2K8       Define XPG7 things.
+//    __USE_XOPEN2K8XSI    Define XPG7 XSI things.
+//    __USE_LARGEFILE	Define correct standard I/O 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 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++.

+// 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 fot 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
+//      array_name[restrict]
+//    GCC 3.1 supports this.

+//
+//    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 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

+//    must consider only the value of __cplusplus when compiling C++.

+//    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 fot 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
+//      array_name[restrict]
+//    GCC 3.1 supports this.
+
+// Describes a char array whose address can safely be passed as the first

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

+//
+//    __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_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 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

+//    compatibility with various implementations of <cstdio>, this test
+//    must consider only the value of __cplusplus when compiling C++.

+// 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 fot 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
+//      array_name[restrict]
+//    GCC 3.1 supports this.
+
+// Describes a char array whose address can safely be passed as the first
+//    argument to strncpy and strncat, as the char array is not necessarily

+//    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.

+//    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

+
+// 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 fot 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
+//      array_name[restrict]
+//    GCC 3.1 supports this.
+
+// Describes a char array whose address can safely be passed as the first
+//    argument to strncpy and strncat, as the char array is not necessarily
+//    a NUL-terminated string.

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

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

+//    __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 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++.
+
+// Get definitions of __STDC_* predefined macros, if the compiler has

+// 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 fot 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.
+

+//    since version 4.9.  Previous versions do not provide generic
+//    selection, even though they might set __STDC_VERSION__ to 201112L,

+//    when testing __STDC_VERSION__ for generic selection support.
+//    On the other hand, Clang also defines __GNUC__, so a clang-specific
+//    check is required to enable the use of generic selection.
