Any 'using' statements in the protected section of a class were previously ignored with dirprot mode, certainly with Java and C#. Also directors - a call to a method being defined in the base class, not overridden in a subcalss, but again overridden in a class derived from the first subclass was not being dispatched correcly to the most derived class - affecting non-scripting languages. Fix for C# is based on recent fix for D.
