State-Changed-Why:
    Confirmed. Here's a simpler testcase:
    --------------------------
    template <typename T>
    struct C {
        void foo (struct X *);
    };
    
    struct X {};
    
    template <typename T>
    void C<T>::foo(struct X *) {}
    -------------------------------
    It's rejected by all versions of gcc. However, if
    one makes C a non-template, then it is accepted. Strange.
    
    I suspect that the language actually mandates this behavior,
    since both icc and cxx (well, both EDG based after all)
    have this behavior as well. I don't know what is right in
    this case.
