I think the testcase is invalid, and the correct one should be:
    
    template <class T> struct Y {
      void member() {
        X<int> c;
        c.prot_data = 2;
      }
    };
     
    template <class S> class X {
      int prot_data;
      template <class T> friend void Y<T>::member();
    };
   
    template class Y<int>;

Here Y<T>::member is declared before it is referenced
in the friend declaration.  This is according to 8.3p1
section of the standard:

  ... When the declarator-id is qualified, the declaration
  shall refer to a previously declared member of the class
  or namespace to which the qualifier refers, ...

I'm working on a fix for the valid case above.
