	* einfo.adb: Flag245 is now used.
	(Is_Primitive_Wrapper, Set_Is_Primitive_Wrapper): Relax the assertion
	check to include functions.
	(Is_Private_Primitive, Set_Is_Private_Primitive): New subprograms.
	(Wrapped_Entity, Set_Wrapped_Entity): Relax the assertion check to
	include functions.
	(Write_Entity_Flags): Move flag Is_Primitive, add Is_Private_Primitive
	to the list of displayed flags.

	* einfo.ads: Update comment on the usage of Is_Primitive_Wrapper and
	Wrapped_Entity. These two flags are now present in functions.
	New flag Is_Private_Primitive.
	(Is_Private_Primitive, Set_Is_Private_Primitive): New subprograms.

	* exp_ch9.adb:
	(Build_Wrapper_Bodies): New subprogram.
	(Build_Wrapper_Body): The spec and body have been moved to in
	Build_Wrapper_ Bodies. Code cleanup.
	(Build_Wrapper_Spec): Moved to the spec of Exp_Ch9. Code cleanup.
	Wrappers are now generated for primitives declared between the private
	and full view of a concurrent type that implements an interface.
	(Build_Wrapper_Specs): New subprogram.
	(Expand_N_Protected_Body): Code reformatting. Replace the wrapper body
	creation mechanism with a call to Build_Wrapper_Bodies.
	(Expand_N_Protected_Type_Declaration): Code reformatting. Replace the
	wrapper spec creation mechanism with a call to Build_Wrapper_Specs.
	(Expand_N_Task_Body): Replace the wrapper body creation
	mechanism with a call to Build_Wrapper_Bodies.
	(Expand_N_Task_Type_Declaration): Replace the wrapper spec
	creation mechanism with a call to Build_Wrapper_Specs.
	(Is_Private_Primitive_Subprogram): New subprogram.
	(Overriding_Possible): Code cleanup.
	(Replicate_Entry_Formals): Renamed to Replicate_Formals, code cleanup.

	* exp_ch9.ads (Build_Wrapper_Spec): Moved from the body of Exp_Ch9.

	* sem_ch3.adb: Add with and use clause for Exp_Ch9.
	(Process_Full_View): Build wrapper specs for all primitives
	that belong to a private view completed by a concurrent type
	implementing an interface.
	
	* sem_ch6.adb (Analyze_Subprogram_Body): When the current subprogram
	is a primitive of a
	concurrent type with a private view that implements an interface, try to
	find the proper spec.
	(Analyze_Subprogram_Declaration): Mark a subprogram as a private
	primitive if the type of its first parameter is a non-generic tagged
	private type.
	(Analyze_Subprogram_Specification): Code reformatting.
	(Disambiguate_Spec): New routine.
	(Find_Corresponding_Spec): Add a flag to controll the output of errors.
	(Is_Private_Concurrent_Primitive): New routine.

	* sem_ch6.ads:
	(Find_Corresponding_Spec): Add a formal to control the output of errors.
