	* sem_ch6.adb (New_Overloaded_Entity): If the new entity is a
	rederivation associated with a full declaration in a private part, and
	there is a partial view that derives the same parent subprogram, the
	new entity does not become visible. This check must be applied to
	interface operations as well.
