Update.
2003-11-17 Jakub Jelinek <jakub@redhat.com>
* posix/regcomp.c (optimize_utf8): Optimize multi-byte chars as
well.
* posix/bug-regex20.c (tests): Add new tests. Multi-byte char
followed by dup operator is expected to be optimized.
* posix/regexec.c (check_node_accept_bytes): Move nrules and j
variables to the block where they are only used, initialize
nrules only immediately before using it.
