	* sem_disp.adb (Check_Controlling_Formals): Anonymous access types
	used in controlling parameters exclude null because it is necessary to
	read the tag to dispatch, and null has no tag.
	(Override_Dispatching_Operation): If the previous operation is inherited
	from an interface, it becomes hidden  and does not participate in later
	name resolution.
