mips/mips.h bug with WCHAR_TYPE?

[Martin Sebor]

FYI: a similar inconsistency is/was in gcc 2.95.2 on AIX, where the patched
<stddef.h> defines wint_t to unsigned int while the system <ctype.h> (which
isn't replaced by gcc) defines wint_t to int. I've been meaning to submit a bug
report on this but haven't so far. Don't know if this is still a problem in the
latest sources.

Regards
Martin

$ grep -n wint_t /usr/include/ctype.h 
101:    typedef int     wint_t;
127:    extern int      is_wctype(wint_t, wctype_t);

$ grep -n wint_t
