Modified files:
	posix          : regexec.c 

Log message:
	(check_dst_limits_calc_pos): Simplify some nested conditionals.  Replace if's
	with a switch statement.
	(check_dst_limits_calc_pos <TYPE_BKREF>): Rename parameter NODE to
	FROM_NODE, it shadows a local variable; don't recurse if FROM_NODE
	does not change in the recursive invocation, fixing an infinite loop
	in the ()\1*\1* regex.
	(sift_states_backward): Fix function comment.
