It's worse than that.  Recently it was pointed out that a named enumeration
type is in scope as soon as its name is seen, and since there is no provision
for incomplete enumerated types, that means that `sizeof(enumtype)' is legal
before the members have been seen... so the size of the type cannot depend
on the values of the members!!  (In X3J11's defence, this probably was not
deliberate.)
