2002-05-21 Isamu Hasegawa <isamu@yamato.ibm.com> * posix/regex.c: Define `inline' as a macro into nothing for the compilers which lack the keyword. * posix/regex.h: (RE_SYNTAX_GNU_AWK): Remove RE_CONTEXT_INVALID_OPS for the compatibility of gawk. * posix/regcomp.c: Add fake implementation of isblank() for the environments which lack the function. Don't use free_charset() in case of non-i18n envs. (build_range_exp): Don't use i18n related code in case of non-i18n envs. (build_collating_symbol): Likewise. (build_equiv_class): Likewise. (build_charclass): Likewise. (re_compile_fastmap_iter): Likewise. (parse_bracket_exp): Likewise. (build_word_op): Likewise. (regfree): Don't use free_charset() in case of non-i18n envs. * posix/regex_internal.h: Remove COMPLEX_BRACKET from re_token_type_t in case of non-i18n envs. Don't define re_charset_t in case of non-i18n envs. Change the type of wcs of re_string_t from wchar_t to wint_t, since we store also WEOF. * posix/regex_internal.c: (re_string_realloc_buffers): Change the type of wcs of re_string_t from wchar_t to wint_t. (re_string_reconstruct): Likewise. (create_ci_newstate): Don't use i18n related code in case of non-i18n envs. (create_cd_newstate): Likewise. 2002-05-24 Ulrich Drepper <drepper@redhat.com> * iconv/loop.c: Fix typo. 2002-05-23 Jakub Jelinek <jakub@redhat.com> * inet/ether_line.c (ether_line): Fix a typo causing only lower 4 bits of each ethernet address byte being assigned. Don't modify what line points to. * inet/tst-ether_aton.c (main): Add ether_line tests. 2002-05-23 Marcus Brinkmann <marcus@gnu.org> * manual/filesys.texi: Don't make readlink example leak memory when readlink fails.
