Update.

2003-11-26  Jakub Jelinek  <jakub@redhat.com>

	* posix/regexec.c (check_subexp_limits): Only check close
	subexpression limitation if one is found.  Formatting.
	(sift_states_backward, check_arrival, check_arrival_add_next_nodes):
	Formatting.
	* posix/bug-regex11.c (tests): Enable most #ifdefed out tests.
	Add new test.
