Update.
* posix/regex_internal.h: Add forward declaration of re_dfa_t. Replace last two parameters of re_string_allocate and re_string_construct with pointer to DFA. (re_dfa_t): Add map_notascii field. * posix/regcomp.c (re_compile_internal): Add call of re_string_construct. (init_dfa): Initialize mpa_notascii. * posix/regex_internal.c: Adjust definitions of re_string_allocate and re_string_construct. Pass DFA to re_string_construct. Adjust definition. Initialize map_notascii field. (build_wcs_upper_buffer): If map_notascii is zero use simplfied method to map ASCII values to upper case. * posix/regex.c: Include localeinfo.h. * posix/regexec.c: Adjust call of re_string_allocate. * locale/langinfo.h: Add _NL_CTYPE_MAP_TO_NONASCII. * locale/localeinfo.h (LIMAGIC): Change value. * locale/categories.def. Add entry for _NL_CTYPE_MAP_TO_NONASCII. * locale/C-ctype.h: Likewise. * locale/programs/ld-ctype.c: Compute whether any mapping maps from ASCII to non-ASCII value. Write out that value.
