Update.
2003-11-12 Jakub Jelinek <jakub@redhat.com> * io/ftw.c (NFTW_NEW_NAME, NFTW_OLD_NAME): Add prototypes. 2003-11-12 Jakub Jelinek <jakub@redhat.com> * posix/tst-regex.c (umemlen): New variable. (test_expr): Add expectedicase argument. Test case insensitive searches as well as backwards searches (case sensitive and insensitive) too. (run_test): Add icase argument. Use it to compute regcomp flags. (run_test_backwards): New function. (main): Cast read to size_t to avoid warning. Set umemlen. Add expectedicase arguments to test_expr. * posix/regex_internal.c (re_string_reconstruct): If is_utf8, find previous character by walking back instead of converting all chars from beginning. 2003-11-12 Jakub Jelinek <jakub@redhat.com> * posix/regex_internal.h (struct re_string_t): Add is_utf8 and mb_cur_max fields. (struct re_dfa_t): Likewise. Reorder fields to make structure smaller on 64-bit arches. (re_string_allocate, re_string_construct): Add mb_cur_max and is_utf8 arguments. (re_string_char_size_at, re_string_wchar_at): Use pstr->mb_cur_max instead of MB_CUR_MAX. * posix/regcomp.c (re_compile_fastmap_iter): Use dfa->mb_cur_max instead of MB_CUR_MAX. (re_compile_internal): Pass new arguments to re_string_construct. (init_dfa): Initialize mb_cur_max and is_utf8 fields. (peek_token, peek_token_bracket): Use input->mb_cur_max instead of MB_CUR_MAX. (parse_expression, parse_bracket_exp, parse_charclass_op): Use dfa->mb_cur_max instead of MB_CUR_MAX. * posix/regex_internal.c (re_string_construct_common): Add mb_cur_max and is_utf8 arguments. Initialize fields with them. (re_string_allocate, re_string_construct): Add mb_cur_max and is_utf8 arguments, pass them to re_string_construct_common. Use mb_cur_max instead of MB_CUR_MAX. (re_string_realloc_buffers): Use pstr->mb_cur_max instead of MB_CUR_MAX. (re_string_reconstruct): Likewise. (re_string_context_at): Use input->mb_cur_max instead of MB_CUR_MAX. (create_ci_newstate, create_cd_newstate): Use dfa->mb_cur_max instead of MB_CUR_MAX. * posix/regexec.c (re_search_internal): Likewise. Pass new arguments to re_string_allocate. (check_matching, transit_state_sb): Use dfa->mb_cur_max instead of MB_CUR_MAX. (extend_buffers): Use pstr->mb_cur_max instead of MB_CUR_MAX. 2003-11-12 Jakub Jelinek <jakub@redhat.com> * posix/Makefile (tests): Add bug-regex19. (bug-regex19-ENV): Add LOCPATH. * posix/bug-regex19.c: New test.
