Also, I've had problems with __builtin_object_size not behaving as documented for GCC: it is sometimes not allowed in a constant expression, even though it always returns a constant. I suspect Jim's original proposal is a better way to go. I'll look into one or two possible improvements that don't involve so many changes to the code.
