This basically says that these structs exist and are defined somewhere. You
need this basically for things like this:
struct b;
struct a{
struct b *b_ptr;
};
struct b{
struct a *a_ptr;
};
The struct can only be dereferenced after it is defined. Also, the storage
size is unknown, so the same applies to inlining and sizeof().
