Update.
* posix/regcomp.c (optimize_utf8): New function. (re_compile_fastmap_iter): Use dfa->mb_cur_max > 1 instead of !icase. (re_compile_internal): Call optimize_utf8 if not case insensitive and in UTF-8 locale. * posix/regex_internal.h: Ifdef out some prototypes if RE_NO_INTERNAL_PROTOTYPES is defined to shut up warnings. * posix/Makefile (tests): Add bug-regex20. (bug-regex20-ENV): Add LOCPATH. * posix/bug-regex20.c: New test. 2003-11-12 Jakub Jelinek <jakub@redhat.com>
