The ifdef around gmtime_r and localtime_r in mingw.h is for __MINGW64_VERSION_MAJOR.
The ifdef around _POSIX_C_SOURCE in git-compat-util.h is for
__MINGW64__.
I'd imagine that plays a role.
winpthreads version on my system is 9.0.0.6246.ae63cde27-1.
The /mingw32/i686-w64-mingw32/include/time.h section related to gtime_r
and localtime_r starts with:
```
#if defined(_POSIX_C_SOURCE) && !defined(_POSIX_THREAD_SAFE_FUNCTIONS)
#define _POSIX_THREAD_SAFE_FUNCTIONS 200112L
#endif
#ifdef _POSIX_THREAD_SAFE_FUNCTIONS
__forceinline struct tm *__CRTDECL localtime_r(const time_t *_Time, struct tm *_Tm) {
return localtime_s(_Tm, _Time) ? NULL : _Tm;
}
__forceinline struct tm *__CRTDECL gmtime_r(const time_t *_Time, struct tm *_Tm) {
return gmtime_s(_Tm, _Time) ? NULL : _Tm;
}
```
