Still not enough; Chris reported another failure offlist. wctype.m4's AC_SUBST
(HAVE_WINT_T) was resulting in an empty string, even though wint_t.m4's
AC_DEFINE(HAVE_WINT_T, 1, ...) was now guessing correctly:
rm -f wctype.h-t wctype.h
{ echo '/* DO NOT EDIT! GENERATED AUTOMATICALLY! */'; \
sed -e 's/@''HAVE_WCTYPE_H''@/0/g' \
-e 's|@''ABSOLUTE_WCTYPE_H''@|"no/such/file/wctype.h"|g' \
-e 's/@''HAVE_WCTYPE_CTMP_BUG''@//g' \
-e 's/@''HAVE_WINT_T''@//g' \
< ./wctype_.h; \
} > wctype.h-t
mv wctype.h-t wctype.h
And from his config.log:
configure:9374: checking for wint_t
configure:9409: gcc -c -g -O2 conftest.c >&5
configure:9416: $? = 0
configure:9431: result: yes
...
## ----------------- ##
## Output variables. ##
## ----------------- ##
...
HAVE_WCTYPE_H='0'
HAVE_WINT_T=''
HAVE__BOOL='0'
...
#define HAVE_WCHAR_T 1
#define HAVE_WINT_T 1
#define HAVE_LONG_LONG 1
The obvious solution (I hope) - only use one of the two substitution methods.

* lib/wctype_.h [HAVE_WINT_T]: Rely on AC_DEFINE.
* m4/wctype.m4 (gl_WCTYPE_H): No need to AC_SUBST(HAVE_WINT_T).
* modules/wctype (Makefile.am): Likewise.
