Oh, no, I didn't mean to suggest that zero was the right size to use;
I agree with you completely that that would be pretty confusing.
Your story is pretty amazing --- I would never have guessed that
people actually *use* the sizeof (struct incomplete) == 1 behavior! I
think it is much more common for people to be unaware that the type is
incomplete; if this hunch is correct, then the behavior your toolbox
folks love will be very confusing. I think an error for arithmetic on
any incomplete type other than (void *) is the right thing.
