	* prj-err.adb (Error_Msg): One more case where a message should be
	considered as a warning.

	* gnatcmd.adb (GNATCmd): Fix previous change, which negated a test.

	* exp_dist.adb (Expand_All_Calls_Remote_Subprogram_Call): Analyze
	calling stubs in the (library level) scope of the RCI locator, where it
	is attached, not in the caller's scope.

	* sem_ch3.adb (Analyze_Object_Declaration): In case of class-wide
	interface object declarations we delay the generation of the equivalent
	record type declarations until its expansion because there are cases in
	which they are not required.            

	* sem_util.adb (Implements_Interface): Add missing support for subtypes.

	* sem_disp.adb (Check_Controlling_Formals): Minor code cleanup plus
	addition of assertion.

	* exp_util.adb (Expand_Subtype_From_Expr): Renamings of class-wide
	interface types require no equivalent constrained type declarations
	because the expanded code only references the tag component associated
	with the interface.
	(Find_Interface_Tag): Improve management of interfaces that are
	ancestors of tagged types.

	* exp_ch3.adb (Expand_N_Object_Declaration): Improve the expansion of
	class-wide object declarations to add missing support to statically
	displace the pointer to the object to reference the tag component
	associated with the interface.

	* exp_disp.adb (Make_Tags) Avoid generation of internally generated
	auxiliary types associated with user-defined dispatching calls if the
	type has no user-defined primitives.
