	* 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.
