(build_charclass_op): Likewise.
* posix/regexec.c (group_nodes_into_DFAstates) <case OP_PERIOD>: Only
set accept bits for single-byte characters.
(group_nodes_into_DFAstates): Don't rely on characters 0 .. 127
being single byte encoded and the rest multi-byte.
* posix/bug-regex19.c (tests): Add new tests.
(do_mb_tests): Initialize t to *test.
(main): Fail even on do_mb_tests errors.

* posix/regexec.c: Add const in a number of places.
* posix/regex_internal.h: Make EPSILON_BIT a macro to help
debugging. Its value isn't important.
2003-11-22 Ulrich Drepper <drepper@redhat.com>
* posix/PTESTS: Fix first test of GA143.
* posix/regex_internal.c (re_dfa_add_node): Add BE, reallocation
isn't likely.
2003-11-21 Ulrich Drepper <drepper@redhat.com>
* posix/regcomp.c (fetch_token): Change interface to match
peek_token. This avoid some copying and reduces code size.
