$ cat t.cpp ;  g++ t.cpp
template <class T>
struct S
{
    int foo () {
        return S<int>::bar ();
    }

private:

    template <class U>
    friend int S<U>::foo ();

    static int bar () { return 0; }
};

int main ()
{
    S<char>().foo ();
}
t.cpp: In member function `int S<T>::foo() [with T = char]':
t.cpp:18:   instantiated from here
t.cpp:13: `static int S<T>::bar() [with T = int]' is private
t.cpp:5: within this context
