	* a-tags.ads, a-tags.adb (Tag_Size): This constant is now internal to
	the package.
	(Object_Specific_Data_Array): This is now internal to the package.
	(Object_Specific_Data): This is now internal to the package.
	(Select_Specific_Data_Element): This is now internal to the package.
	(Select_Specific_Data_Array): This is now internal to the package.
	(Select_Specific_Data): This is now internal to the package.
	(Offset_To_Top_Function_Ptr): This is now public.
	(To_Offset_To_Top_Function_Ptr): Removed.
	(Storage_Offset_Ptr,To_Storage_Offset_Ptr): These declarations are now
	 local to subprogram Offset_To_Top.
	(Predefined_DT): Removed.
	(Typeinfo_Ptr): Removed.
	(OSD): This function is now internal to this package.
	(SSD): This function is now internal to this package.
	(DT): New function that displaces the pointer to the table of primitives
	 to get access to the enclosing wrapper record.
	(IW_Membership): Code cleanup.
	(Offset_To_Top): Code cleanup.
	(Predefined_DT): Removed.
	(Register_Interface_Tag): Removed.
	(Set_Interface_Table): Removed.
	(Set_Offset_Index): Removed.
	(Set_Offset_To_Top): Code cleanup.
	(Set_OSD): Removed.
	(Set_Signature): Removed.
	(Set_SSD): Removed.
	(Set_Tagged_Kind): Removed.
	(Typeinfo_Ptr): Removed.
	(TSD): Removed.
	(Displace): Add missing check on null actual.

	* exp_disp.ads, exp_disp.adb
	(Select_Expansion_Utilities): Removed.
	(Build_Common_Dispatching_Select_Statements): Moved to exp_atags.
	(Expand_Dispatching_Call): Update calls to Get_Prim_Op_Address because
	the interface requires a new parameter.
	(Make_Disp_Asynchronous_Select_Spec, Make_Disp_Conditional_Select_Spec,
	Make_Disp_Get_Prim_Op_Kind_Spec, Make_Disp_Timed_Select_Spec): Replace
	calls to subprograms Build_T, Build_S, etc. by the corresponding code.
	Done to remove package Select_Expansion_Utilities.
	(Make_DT): New implementation for statically allocated dispatch tables.
	(Make_Secondary_DT): Moved to the scope of Make_DT.
	(Register_Primitive): Code cleanup plus incoporate the use of the new
	function DT_Address_Attribute.
	(Expand_Interface_Thunk): The profile of this subprogram has been
	changed to return the Thunk_Id and the corresponding code.
	(Fill_DT_Entry): Removed. Its functionality is now provided by
	subprogram Register_Primitive.
	(Fill_Secondary_DT_Entry): Removed. Its functionality is now provided by
	subprogram Register_Primitive.
	(Register_Primitive): New subprogram that incorporates the previous
	functionalities of Fill_DT_Entry and Fill_Secondary_DT_Entry.
	(Build_Common_Dispatching_Select_Statements): Remove formal Typ. This
	was only required to call Make_DT_Access_Action, which is now removed.
	(Ada_Actions): Removed
	(Action_Is_Proc): Removed
	(Action_Nb_Arg): Removed
	Replace all the calls to Make_DT_Access_Action by direct calls to
	Make_Procedure_Call_Statement or Make_Function_Call.
	(Set_DTC_Entity_Value): New subprogram.
	(Set_All_DT_Position): Add call to new subprogram Set_DTC_Entity_Value.
	(Expand_Interface_Thunk): Add missing support for primitives that are
	functions with a controlling result (case in which there is no need
	to generate the thunk).

	* exp_atag.ads, exp_atag.adb
	(Build_DT): New subprogram that displaces the pointer to reference the
	base of the wrapper record.
	(Build_Typeinfo_Offset): Removed.
	(RTE_Tag_Node): Removed.
	(Build_Common_Dispatching_Select_Statements): Moved here from exp_disp
	(Build_Get_RC_Offset): Removed.
	(Build_Inherit_Predefined_Prims): Removed.
	(Build_Inherit_TSD: Removed.
	(Build_New_TSD): Removed.
	(Build_Set_External_Tag): Removed.

	(Build_Set_Prim_Op_Address): Add documentation.
	(Build_Set_TSD): Removed.

	* rtsfind.ads, rtsfind.adb
	(Load_Fail): If load fails and we are not in configurable run-time
	mode, then raise Unrecoverable_Error.
	(Text_IO_Kludge): Generate an error message if a run-time library is
	not available in a given run-time (ie. zfp run-time).
	(RTE_Record_Component): Add code to check that the component we search
	for is not found in two records in the given run-time package.
	(RE_DT_Offset_To_Top_Size, RE_DT_Predef_Prims_Size): Removed
	(RE_DT_Predef_Prims_Offset): New entity
	(RE_Static_Offset_To_Top): New entity
	(RE_HT_Link): New entity.
