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.
