One potential solution is to factor the new definition of 'f' into another 
base class, e.g.,

template<typename T>
struct test_current_case {
  static int f(const T& t)
  {
    return t;
  }
};

template<typename T, typename base>
struct test_using : public test_current_case<T>, public base
{
  using base::f;
  using test_current_cast<T>::f;
};

I remember trying this, and I think it might have worked with GCC 2.95.3, but 
I'm not entirely sure :)
