wctype.h port to IRIX 5.3

[Paul Eggert]

I installed this to make it easier to port wctype.h to IRIX 5.3.

2007-01-04  Paul Eggert  <address@hidden>

        * lib/wctype_.h (_ctmp_) [HAVE_WCTYPE_CTMP_BUG]: Now of type wchar_t,
        not wint_t.  Also, include <ctype.h>, to fix another IRIX bug.
        * m4/wctype.m4 (gl_WCTYPE_H): Likewise.
        Problems reported by Georg Schwarz for IRIX 5.3.
