184 – Cannot forward reference typedef within struct

struct vegetarian {
	carrots areYummy;
}
typedef ptrdiff_t carrots;
--
The above code fails to compile, producing the error "size of type ptrdiff_t is not known" twice.
Changing the typedef to an alias or placing it before the struct causes it to compile correctly.
I can't think of a good reason for why this would be an actual limitation, so I think it's a bug.
