Perhaps you could elaborate further on the distinction here?

I just thought of one other thing.  Please tell me what
is supposed to happen with

	struct A { virtual void foo(); int x : 31; };
	struct B : public A { unsigned int x : 1; };

If sizeof(B) == 8

It should be 12.

This is one of the bugs I recently discovered in G++'s ABI implementation;
it does in fact make sizeof(B) == 8, even though it shouldn't.
