State-Changed-Why:
    Nathan, I see what you are saying but I think the code is
    still legal. The applicable ctor is attempting to create
    a const qualified _reference_ to function type, which is
    a valid type. In fact, other compilers like Comeau/EDG
    instanciate the constructor with [T = void(void)]. 
    GCC compiles the code, but applies the default conversion
    too soon, so instanciates the template with [T = (void)(*)(void)]
    which is wrong. If you agree, we can rework a code snippet
    which fails if T is a function pointer so that we can
    properly detect the bug.
