I think the rules may have changed.  All of my compilers accept the
following, but it may be incorrect.  I haven't had any success reading
CD2; so, some help there would also be appreciated.

struct A {
 friend A f (A const&);
 };
// A f (A const&);
A (*p)(A const&) = f;
void g () {
 A a;
 f(a);
 }

Are one or both uses of f now invalid without the commented out
declaration?
