Fixes compiling peXXigen under MAC OS/X where the wcsncasecmp function is not available.
* configure.ac (AC_CHECK_HEADERS): Add wctype.h. * configure: Regenerate. * config.in: Regenerate. * peXXigen.c: Include wctype.h if HAVE_WCTYPE_H is defined. (u16_mbtowc): Use wint_t types if HAVE_WCTYPE_H is defined. (rsrc_cmp): Use towlower instead of wcsncasecmp if HAVE_WCTYPE_H is defined.
