Apparently <wctype.h> assumes you have included another include
file that #defines _P.  I assume that file is <ctype.h>; if not,
please let me know.

It looks like we should be using wchar_t there, not wint_t.

This looks like an error in applying the patch; it says "win_t"
not "wint_t".

Could you please try the following patch instead?

If you don't have the Autotools installed, please just try the patch
to lib/wctype_.h.  Then type "make clean", then (cd lib; make wctype.h);
then edit wctype.h to assume that HAVE_WCTYPE_CTMP_BUG is 1; then
type "make".

Thanks.
