TestConfiguration returns int, not bool. This mistake is relatively
harmless on signed-char machines but would lead to core dump in thedeadlock detection code if char is unsigned. Amazingly, this bug hasbeen here since 7.1 and yet wasn't reported till now. Thanks to RobertBruccoleri for providing the opportunity to track it down.
