If you just forward declare an enum/struct, it has an incomplete type, so you
cannot use it inside an aggregate. In fact, you can't do much with that until
it's completed, except creating a pointer to it. E.g. applying sizeof to an
incomplete type is forbidden. With my patch, we behave the same as clang.
Clearly a "duh" moment for me.
OK for the trunk.
