	timed selects.
	(Extract_Dispatching_Call): Extract the entity of the name of a

	The dispatch table will be inherited by the object implementing the
	interface.
	(Copy_Secondary_DTs): Add documentation.

	dispatch tables.
	(Build_Anonymous_Access_Type): Removed.

	to build an anonymous access type. This allows further cleanup in the
	code generated by the expander.
	(Expand_Interface_Conversion): If the actual is an access type then
	build an internal function to handle the displacement. If the actual
	is null this function returns null because no displacement is
	required; otherwise performs a type conversion that will be
	expanded in the code that returns the value of the displaced actual.
	(Expand_Interface_Actuals): Avoid the generation of unnecessary type
	conversions that have no effect in the generated code because no
	displacement is required. Code cleanup; use local variables to
	avoid repeated calls to the subprogram directly_designated_type().

	* exp_util.ads, exp_util.adb (Is_Predefined_Dispatching_Operation):
	Classify the primitive operations used in dispatching selects as
	predefined.

	directly implements a limited interface or extends a type that
	implements a limited interface.
	(Build_Task_Image_Function): Change Subtype_Mark to Result_Definition.
	(Expand_Subtype_From_Expr): Do not build actual subtype if the
	expression is limited.
	(Find_Interface_Tag): Add code to handle class-wide types and
	entities from the limited-view.

	* rtsfind.ads: Add entries in RE_Id and RE_Unit_Table for
	Get_Entry_Index, Get_Prim_Op_Kind, POK_Function, POK_Procedure,
	POK_Protected_Entry, POK_Protected_Function, POK_Protected_Procedure,
	POK_Task_Entry, POK_Task_Procedure, Prim_Op_Kind, Set_Entry_Index,
	Set_Prim_Op_Kind.

	* sem_ch9.adb (Analyze_Triggering_Alternative): Check for legal type
	of procedure name or prefix that appears as a trigger in a triggering
	alternative.

	* uintp.ads: Introduce constants Uint_11 and Uint_13.

	    Javier Miranda  <miranda@adacore.com>

	* exp_ch4.adb (Expand_N_In): Replace test of expression in its own
	type by valid test and generate warning.
	(Tagged_Membership): Generate call to the run-time
	subprogram IW_Membership in case of "Iface_CW_Typ in Typ'Class"
	Change formal name Subtype_Mark to Result_Definition in several calls to
	Make_Function_Specification.
	(Expand_Allocator_Expression): Add tests for suppression of the AI-344
	check for proper accessibility of the operand of a class-wide allocator.
	The check can be left out if checks are suppressed or if the expression
	has a specific tagged type whose level is known to be safe.

	* exp_ch5.adb (Expand_N_Assignment_Statement): Simplify the code that
	generates the run-time check associated with null-excluding entities.
	(Expand_N_Return_Statement): Add tests to determine if the accessibility
	check on the level of the return expression of a class-wide function
	can be elided. The check usually isn't needed if the expression has a
	specific type (unless it's a conversion or a formal parameter). Also
	add a test for whether accessibility checks are suppressed. Augment
	the comments to describe the conditions for performing the check.
