Update.
* posix/Makefile: Add rules to build and run bug-regex2. 2001-02-10 Jakub Jelinek <jakub@redhat.com> * posix/regex.c (convert_mbs_to_wcs): Change is_binary to char *. (regex_compile): Likewise. (FREE_VARIABLES): Don't free is_binary1 and is_binary2. (re_match_2_internal): Use just is_binary instead of two variables. Use REGEX_TALLOC to allocate it and FREE_VAR to free on failure. 2001-02-09 Ulrich Drepper <drepper@redhat.com>
