Old Synopsis: gcc 3.3: "error: template definition of non-template"
New Synopsis: [3.3 regression] matching of conversion operators

State-Changed-Why:
    True. It's a regression on mainline. Here's a reduced
    testcase:
    ------------------------------------
    template <typename X> struct C1{};
    
    template <typename X>
    struct C2 {
        template<typename Y> operator C1<Y>();
        template<typename Y> operator C2<Y>();
    };
    
    
    template<typename X> template<typename Y>
    C2<X>::operator C1<Y>()
    {
      return C1<Y>();
    }
    ---------------------------------
    
    gcc3.3 complains when seeing the definition of the 
    conversion operator.It is apparently confused by the
    second conversion operator, since if I remove that 
    declaration, everything is fine. 3.2.1 and 2.95 accept 
    the code as is.
