- 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. */
