g++: 'protected' member function cannot be declared friend



g++ issues a diagnostic on this test case.
Section 11.4 does not address this issue, but I think that this is a g++ bug. The
fact that a member function itself is 'protected' should not prevent it from accessing members of other
classes where it is declared as 'friend'.



% cat protected.C class FOO { protected: void Push(); };

class S {
        friend void FOO::Push();
};


% g++ -c protected.C protected.C:3: error: 'void FOO::Push()' is protected protected.C:7: error: within this context
