Update.
2003-11-24 Jakub Jelinek <jakub@redhat.com> * posix/regex_internal.h (re_token_t): Add word_char bit. Add comment. (re_dfa_t): Add sb_char field. (bitset_mask): New function. * posix/regcomp.c (free_dfa_content): Free sb_char. (init_dfa): Don't initialize word_char unnecessarily. Initialize sb_char. (duplicate_node): Don't duplicate !word_char CHARACTERs with NEXT_WORD_CONSTRAINT constraint or word_char CHARACTERs with NEXT_NOTWORD_CONSTRAINT. Return -1 in *new_idx instead. (duplicate_node_closure): Handle clone_dest == -1 from duplicate_node. (peek_token): Initialize word_char bit. (parse_expression, parse_dup_op): Add comments. (parse_bracket_exp): Don't set bitmask bits for multi-byte char starting bytes here at the beginning. Mask off the bits right before creating SIMPLE_BRACKET. (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.
