Update.
2002-04-26 Isamu Hasegawa <isamu@yamato.ibm.com> * posix/regcomp.c (re_compile_fastmap_iter): Fix fastmap in case of not _LIBC and RE_ENABLE_I18N. (build_range_exp): Implement for not _LIBC. (build_collating_symbol): Likewise. (parse_bracket_exp): Unify redundant error handlings. Don't erase mbcset for non matching list in multibyte envs. (build_word_op): Add '_' to matching list for \w operator. * posix/regex_internal.c (re_string_construct): Invoke build_upper_buffer in case of not RE_ENABLE_I18N. (re_string_reconstruct): Don't touch cur_state in case of not RE_ENABLE_I18N. * posix/regex_internal.h (attribute_hidden): New macro in case of not _LIBC. (re_charset_t): Define range_starts/ends in case of not _LIBC. * posix/regexec.c (sift_states_iter_mb): Hide in case of not RE_ENABLE_I18N. (transit_state_mb): Likewise. (check_node_accept_bytes): Implement the code evaluating range expression in case of not _LIBC. (find_collation_sequence_value): Hide in case of not _LIBC. 2002-04-26 Jakub Jelinek <jakub@redhat.com> * sysdeps/unix/sysv/linux/sparc/sparc32/semctl.c: Copied from i386/semctl.c. (__old_semctl, __new_semctl): Only use va_arg if the argument will be used.
