State-Changed-From-To: open->closed
State-Changed-By: aoliva
State-Changed-When: Sun Nov 25 10:47:14 2001
State-Changed-Why:
    Your code is missing the template brackets and arguments when referencing a previously-declared template function.  Try:
    template <class S> friend int f<T,S>(T a, S b);
