glibc/wctype/wctype.h
Ulrich Drepper 49f2be5b0e Update. 
* ctype/Versions: Add __ctype32_tolower and __ctype32_toupper.
	* ctype/ctype-info.c: Define __ctype32_tolower and __ctype32_toupper.
	* locale/C-ctype.c: Add _nl_C_LC_CTYPE_toupper32 and
	_nl_C_LC_CTYPE_tolower32 tables.
	Don't compile it names of 14652 classes and maps.
	* locale/langinfo.h: Define _NL_CTYPE_TOUPPER32 and
	_NL_CTYPE_TOLOWER32.
	* locale/lc-ctype.c (_nl_postload_ctype): Initialize __ctype32_toupper
	and __ctype32_tolower.
	* locale/programs/ld-ctype.c (struct locale_ctype_t): Add map32.
	(ctype_output): Write out map32 values.
	(allocate_arrays): Compute mapping tables correctly.
	* wctype/wcfuncs.c (towlower): Use __ctype32_tolower.
	(towupper): Use __ctype32_toupper.
	* wctype/wctype.h: Optimize towupper and towlower for values < 256.
