Subject: Fix bug reported by Bruno Haible in
 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00228.html> where
 quotearg.c didn't compile on Mac OS X 10.2 because it lacks <wchar.h> and
 wint_t. * lib/wctype_.h (__wctype_wint_t): New type. Include <stdio.h>,
 <time.h>, <wchar.h> only if HAVE_WINT_T. (iswalnum, iswalpha, iswblank,
 iswcntrl, iswdigit, iswgraph): (iswlower, iswprint, iswpunct, iswspace,
 iswupper, ixwxdigit): Arg is now of type __wctype_wint_t, not wint_t. *
 m4/wctype.m4 (gl_WCTYPE_H): Require gt_TYPE_WINT_T, and substitute
 HAVE_WINT_T. * modules/wctype (Files): Add m4/wint_t.m4. (wctype.h):
 Substitute HAVE_WINT_T.
