Given that either sizes have to match the enum base or be unsized, it isn't clear to me the circumstances under which there is really going to be a difference. I guess if you have a >32 bit enum base width and then added two unsized values that the implementation treated as 32 bits integers (legal) and that caused a 32 bit overflow you might get a difference. A bit obscure, but possible.
