  43      <wchar.h> -> <stdlib.h> -> <stdint.h>, and the latter includes <wchar.h>,
  44      once indirectly <stdint.h> -> <sys/types.h> -> <inttypes.h> -> <wchar.h>

  46      therefore we cannot provide the function overrides; instead include only
  47      the system's <wchar.h>.
  48    - With MinGW 3.22, when <string.h> includes <wchar.h>, only some part of
  49      <wchar.h> is actually processed, and that doesn't include 'mbstate_t'.
  50    - On IRIX 6.5, similarly, we have an include <wchar.h> -> <wctype.h>, and
  51      the latter includes <wchar.h>.  But here, we have no way to detect whether
