	* exp_intr.adb (Expand_Unc_Deallocation): If GIGI needs an actual
	subtype to compute the size of the designated object at run-time,
	create such a subtype and store it in the Actual_Designated_Subtype
	attribute of the N_Free_Statement.
	Generate itype for classwide designated object in both cases of
	user-specified storage pool: specific and class-wide, not only in the
	specific case.
	Raise CE when trying to set a not null access type object to null.
	(Expand_Dispatching_Constructor_Call): Retrieve subprogram actual with
	an explicit loop, because freeze nodes make its position variable.

	* sem_intr.adb (Check_Intrinsic_Call): Given warning for freeing not
	null object.
