	* exp_ch3.adb (Expand_N_Object_Declaration): Rewrite an object
	declaration of the form "X : T := Func (...);", where T is
	controlled, as a renaming.
	* a-strunb-shared.adb (Finalize): Set the Unbounded_String Object
	to be an empty string, instead of null-ing out the Reference.
	* exp_util.adb (Needs_Finalization): Remove redundant code.
