	* exp_intr.adb (Expand_Unc_Deallocation): If the designated type is
	controlled, indicate the expected type of the dereference that is
	created for the call to Deep_Finalize, to prevent spurious errors when
	the designated type is private and completed with a derivation from
	another private type.
