   - Inside glibc and uClibc header files, but not MinGW.
   - On HP-UX 11.00 we have a sequence of nested includes
     <wchar.h> -> <stdlib.h> -> <stdint.h>, and the latter includes <wchar.h>,
     once indirectly <stdint.h> -> <sys/types.h> -> <inttypes.h> -> <wchar.h>
     and once directly.  In both situations 'wint_t' is not yet defined,
     therefore we cannot provide the function overrides; instead include only
     the system's <wchar.h>.
   - With MinGW 3.22, when <string.h> includes <wchar.h>, only some part of
     <wchar.h> is actually processed, and that doesn't include 'mbstate_t'.
   - On IRIX 6.5, similarly, we have an include <wchar.h> -> <wctype.h>, and
     the latter includes <wchar.h>.  But here, we have no way to detect whether
     <wctype.h> is completely included or is still being included.  */
