8690e634 JK |
42 | - On HP-UX 11.00 we have a sequence of nested includes |
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> | |
45 | and once directly. In both situations 'wint_t' is not yet defined, | |
46 | therefore we cannot provide the function overrides; instead include only | |
47 | the system's <wchar.h>. | |
49e4877c PA |
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'. | |
8690e634 JK |
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 | |
52 | <wctype.h> is completely included or is still being included. */ | |
