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.
