Oh heck yeah. I'm not sure about the other reasons, but this one alone
takes the cake.
I wouldn't say it should return an int, though: IMO sizeof(x) ought to
be treated just like any other numeric constant in C - that is,
interpreted as signed or unsigned as the situation dictates. Why they
introduced this gratuitous unorthogonality, I have no idea. Well, maybe
that's not strictly true... I _can_ guess. Probably "sizeof always
yields a positive number so we should force its type to be unsigned."
But that makes exactly as much sense as "4 always yields a positive
number so we should force its type to be unsigned," which is stupid.
