37 | - On HP-UX 11.00 we have a sequence of nested includes |
38 | <wchar.h> -> <stdlib.h> -> <stdint.h>, and the latter includes <wchar.h>, | |
39 | once indirectly <stdint.h> -> <sys/types.h> -> <inttypes.h> -> <wchar.h> | |

41 | therefore we cannot provide the function overrides; instead include only | |
42 | the system's <wchar.h>. | |
43 | - On IRIX 6.5, similarly, we have an include <wchar.h> -> <wctype.h>, and | |
