State-Changed-Why:
    Confirmed, that is I can confirm that it does no longer
    compile, but I don't know for sure whether the code is
    legal. A further extract is this:
    ------------------------------
    template<bool>
    struct Outer {
        template <typename T> struct Inner {};
    };
    
    template <bool b, typename T>
    struct X : Outer<b>::template Inner<T>
    {};
    -----------------------------
    This used to compile with the old parser, but does not
    any more. It _does_ compile, however, when you drop the
    "template" in Outer<b>::template Inner<T>.
    
    Gaby, you knew about this stuff. What's legal and what is
    not?
    
    W.
