[PATCH v6 2/4] curses: Fixes compiler error that complain don't have langinfo.h on msys2/mingw

[Yonggang Luo]

msys2/mingw lacks the POSIX-required langinfo.h.

gcc test.c -DNCURSES_WIDECHAR -I/mingw64/include/ncursesw -pipe -lncursesw -lgnurx -ltre -lintl -liconv
test.c:4:10: fatal error: langinfo.h: No such file or directory
    4 | #include <langinfo.h>
      |          ^~~~~~~~~~~~
compilation terminated.

So we using g_get_codeset instead of nl_langinfo(CODESET)

If you're removing use of nl_langinfo / langinfo.h then you need
to also update configure, because it is checking for this function
and header file when validating curses library support.

The change of configure are waiting for meson 0.56, so I didn't post that
yet And this patch
is a pre-request for msys2/mingw support and won't hurt other platform

We are converting everything to meson, so I am not willing to change
configure this time

I don't see why the configure change has any dependancy on meson 0.56.
It just requires you to remove the mentioned header file and function
from the configure check. This patch needs to include that or it is
incomplete IMHO

Daniel

I agree, moving the check to Meson is waiting for 0.56 but for now the
configure check needs to be maintained.

[PATCH v6 4/4] win32: Simplify gmtime_r detection not depends on if _POSIX_C_SOURCE are defined on msys2/mingw

[Yonggang Luo]

We remove the CONFIG_LOCALTIME_R detection option in configure, and move the check
existence of gmtime_r from configure into C header and source directly by using macro
`_POSIX_THREAD_SAFE_FUNCTIONS`.
Before this patch, the configure script are always assume the compiler doesn't define
_POSIX_C_SOURCE macro at all, but that's not true, because thirdparty library such
as ncursesw may define -D_POSIX_C_SOURCE in it's pkg-config file. And that C Flags will
added -D_POSIX_C_SOURCE into each QEMU_CFLAGS. And that's causing the following compiling error:

After this patch, whenever ncursesw or other thirdparty libraries tried to define or not
define  _POSIX_C_SOURCE, the source will building properly. Because now, we don't make any
assumption if _POSIX_C_SOURCE are defined. We solely relied on if the macro `_POSIX_THREAD_SAFE_FUNCTIONS`
are defined in msys2/mingw header.

The _POSIX_THREAD_SAFE_FUNCTIONS are defined in mingw header like this:

```
#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;
}
__forceinline char *__CRTDECL ctime_r(const time_t *_Time, char *_Str) {
  return ctime_s(_Str, 0x7fffffff, _Time) ? NULL : _Str;
}
__forceinline char *__CRTDECL asctime_r(const struct tm *_Tm, char * _Str) {
  return asctime_s(_Str, 0x7fffffff, _Tm) ? NULL : _Str;
}
