	* Make-generated.in: Minor cleanup of all targets: use
	MOVE_IF_CHANGE to put generated files in place, to avoid useless
	recompilations.

	* exp_disp.adb (Expand_Dispatching_Call): For functions returning
	interface types add an implicit conversion to the returned object
	to force the displacement of the pointer to the returned object
	to reference the corresponding secondary dispatch table. This
	is needed to handle well combined calls involving secondary
	dispatch tables (for example Obj.Prim1.Prim2).
	* exp_ch4.adb (Expand_Allocator_Expression): Declare internal
	access type as access to constant or access to variable depending
	on the context. Found working in this ticket.

	* checks.adb (Apply_Predicate_Check): Do not apply check to
	actual of predicate checking procedure, to prevent infinite
	recursion.
