Yes! And there is the true root of the problem. If the System unit changes, all units depending on that unit must be recompiled, Borland-supplied or otherwise. Since the System unit *always* changes between versions, there is no compatibility between units compiled under different versions of the compiler. This is the actual reason why Borland said, "No [there won't be backward compatibilty]." Under the circumstances, it would be quite difficult.
