compat/regex: move stdlib.h up in inclusion chain
In Linux with musl libc, we have this inclusion chain: compat/regex/regex.c:69 `-> compat/regex/regex_internal.h `-> /usr/include/stdlib.h `-> /usr/include/features.h `-> /usr/include/alloca.h In that inclusion chain, `<features.h>` claims it's _BSD_SOURCE compatible when it's NOT asked to be either {_POSIX,_GNU,_XOPEN,_BSD}_SOURCE, or __STRICT_ANSI__. And, `<stdlib.h>` will include `<alloca.h>` to be compatible with software written for GNU and BSD. Thus, redefine `alloca` macro, which was defined before at compat/regex/regex.c:66. Considering this is only compat code, we've taken from other project, it's not our business to decide which source should we adhere to. Include `<stdlib.h>` early to prevent the redefinition of alloca. This also remove a potential warning about alloca not defined on: #undef alloca Helped-by: Ramsay Jones <ramsay@ramsayjones.plus.com> Signed-off-by: Đoàn Trần Công Danh <congdanhqx@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
