Throw error if address overflows in extended mode This may or may not cause extra problems due to sloppiness in dealing with calculations that overflow in 16 bits. However, presumably it is a good idea so unless something major pops up, it seems like a good idea. Thanks to Erik G <erik@6809.org> for the patch.
