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
