CLASS_NAME and EXTRA. Add EXTRA to the result, not only _.
(peek_token): accept \s and \S as OP_SPACE and OP_NOTSPACE.
(parse_expression): replace build_word_op with
build_charclass_op, add new arguments, accept OP_SPACE
and OP_NOTSPACE.
* posix/regex_internal.h (re_token_type_t): Add OP_SPACE
and OP_NOTSPACE.
2003-09-20 Paolo Bonzini <bonzini@gnu.org>
* posix/regcomp.c (peek_token): Don't look back for ( or |
to check whether to treat a caret as special. It fails
for the (extended) regex \(^.
(parse, parse_reg_exp): Pass RE_CARET_ANCHORS_HERE to fetch_token.
* posix/regex.h: Define RE_CARET_ANCHORS_HERE.
* posix/regexec.c: Check out of bounds value before shifting.
* posix/regex_internal.h: Define __attribute for non-gcc.
2003-06-12 H.J. Lu <hongjiu.lu@intel.com>
* posix/transbug.c (run_test): Return 1 for failure.
(do_test): Compare only if run_test is successful.
2003-06-12 Simon Josefsson <jas@extundo.com>
* argp/argp.h [!__THROW]: Define if undefined.
* posix/transbug.c: New file.
* inet/Makefile (aux): Add check_pf.
* include/ifaddrs.h: Add prototype for __check_pf.
* sysdeps/generic/check_pf.c: New file.
* sysdeps/unix/sysv/linux/check_pf.c: New file.
* inet/rcmd.c (rresvport_af): Avoid using invliad values. Wrap
around in search if port IPPORT_RESERVED/2 has been test.
2002-02-20 Paolo Bonzini <bonzini@gnu.org>
* posix/regcomp.c: Remove inclusions.
* posix/regexec.c: Likewise.
* posix/regex_internal.c: Likewise.
* posix/regex_internal.h: Add inclusions here.
* posix/regex.c: Only include sys/types.h before regex.h. Include
regex_internal.h here. Include regex_internal.c before regcomp.c
and regexec.c (might expose more opportunities to the C compiler).
* posix/regcomp.c (parse_expression): Fix construct rejected by SGI CC.
* posix/regex_internal.h [!_LIBC] (__mempcpy): Fix typo.
[!_LIBC] (__wcrtomb): New definition.
[!_LIBC]: Conditionalize enabling of I18N on HAVE_WCSCOLL and
HAVE_LOCALE_H as well.
