2.

always

Here is an actual simple test case instead of the mess provided before:

class Abuse<T> {}

class X {
        static int Main ()
        {
                Abuse<string> a = new Abuse<string> ();
                if (a && null)
                        return 1;
                return 0;
        }
}

There is a patch from mcs that I believe we need to port to gmcs and
might eliminate this problem (the recent Null code from Marek).

Miguel, I tested your code with final version of csc 2. And it reports
same error as we do.

Thanks, am going to flag this as a NOTABUG.
