The language rules say that you cannot return non-pointer
values from operator->.  So why does G++ (1.36.1) wait until
it sees some *use* of a blatantly bogus declaration of an operator->
before it flags an error?

// rfg

struct c1 {
	int f1;
	int f2;

	c1 ();
	int get_f1 () { return f1; }
};

struct c2 {
	c1 c1_member;

	c1 & operator -> () { return c1_member; } // should get an error here!
};

int
main ()
{
	c2 c2_object;
	int i;

	i = c2_object->get_f1 ();    // actually gets an error here!
	i = c2_object->f1;           // actually gets an error here!
}
