Don't allow non-existant ISO-8859-12 charset. Add support for Windows singlebyte codepages. On Cygwin, add support for GBK, CP949, and BIG5. On Cygwin, call __set_ctype() in case the catorgy is LC_CTYPE. Don't set _current_category and _current_locale. * libc/stdlib/Makefile.am (GENERAL_SOURCES): Add sb_charsets.c. * libc/stdlib/Makefile.in: Regenerate. * libc/stdlib/local.h: Add prototype for __locale_charset. Add prototypes for __mbtowc and __wctomb pointers. Add prototypes for charset-specific _wctomb_r and _mbtowc_r functions. Declare tables and functions from sb_charsets.c. * libc/stdlib/mbtowc_r.c (__mbtowc): Define. Set to __ascii_mbtowc by default. (_mbtowc_r): Just call __mbtowc from here. (__ascii_mbtowc): New function. (__iso_mbtowc): New function. (__cp_mbtowc): New function. (__utf8_mbtowc): New function. (__sjis_mbtowc): New function. Disable on Cygwin. (__eucjp_mbtowc): New function. Disable on Cygwin. (__jis_mbtowc): New function. Disable on Cygwin. * libc/stdlib/sb_charsets.c: New file, adding singlebyte to UTF conversion tables for all ISO and CP charsets. (__iso_8859_index): New function. (__cp_index): New function. * libc/stdlib/wctomb_r.c (__wctomb): Define. Set to __ascii_wctomb by default. (_wctomb_r): Just call __wctomb from here. (__ascii_wctomb): New function. (__utf8_wctomb): New function. (__sjis_wctomb): New function. Disable on Cygwin. (__eucjp_wctomb): New function. Disable on Cygwin. (__jis_wctomb): New function. Disable on Cygwin. (__iso_wctomb): New function. (__cp_wctomb): New function.
