* libc/string/local.h: New file. * libc/string/wcswidth.c (wcswidth): Convert japanese wide characters to Unicode here. Handle surrogate pairs for UTF-16 systems. Call __wcwidth rather than wcwidth. * libc/string/wcwidth.c: New implementation using Markus Kuhn's wcwidth implementation for Unicode. (bisearch): New static function. (__wcwidth): New function. Take wint_t rather than wchar_t as parameter to allow full Unicode handling on UTF-16 systems. Move old wcwidth implementation here for non-multibyte aware systems. (wcwidth): Convert japanese wide characters to Unicode here. Call __wcwidth rather than using iswprint/iswcntrl.

#include <_ansi.h>
* libc/ctype/jp2uc.c: Skip all definition if defined __CYGWIN__. (__jp2uc): Change the scope to static function. * libc/ctype/local.h (_jp2uc): Define as macro if defined __CYGWIN__. * libc/string/local.h (_jp2uc): Include ../ctype/local.h.

int __wcwidth (wint_t);
* libc/string/wcwidth.c: Optimize for speed. * libc/locale/locale.c (lc_ctype_cjk_lang): New static int. (loadlocale): In case of setting LC_CTYPE, set lc_ctype_cjk_lang to 1 if the language is "jp", "ko", or "zh", to 0 otherwise. (__locale_cjk_lang): New function. * libc/string/local.h (__locale_cjk_lang): Declare. * libc/string/wcwidth.c: Fix comments. (__wcwidth): Handle CJK Ambiguous Width characters according to setting returned by __locale_cjk_lang.

2013-12-10 Jeff Johnston <jjohnstn@redhat.com> * acconfig.h: Add _HAVE_CC_INHIBIT_LOOP_TO_LIBCALL. * newlib.hin: Ditto. * configure: Regenerate. * configure.in: Add setting of _HAVE_CC_INHIBIT_LOOP_TO_LIBCALL. * libc/string/local.h: Add check for _HAVE_CC_INHIBIT_LOOP_TO_LIBCALL and set __inhibit_loop_to_libcall macro appropriately. * libc/string/memmove.c: Use __inhibit_loop_to_libcall macro in function declaration. * libc/string/memset.c: Ditto.
