        template<class T2> struct B { 
            template<class T3> void mf1(T3);
            void mf2(); 
        }; 
    }; 

    template<> template<class X> 
        struct A<int>::B {
            template<class T> void mf1(T);
    }; 

    template<> template<> template<class T> 
        void A<int>::B<double>::mf1(T t) { } 
    template<class Y> template<> 
        void A<Y>::B<double>::mf2() { }
