actually, kenc is pretty good about all these. if you have
struct fu {void x;};
and take sizeof(struct fu), that will give a diagnostic error.
the reason i avoided it was to not mess with the grammer, but if this is a
common thing, maybe it's no big deal.
though as charles points out, it is a bit of a waste of time.
