	* sem_res.adb (Resolve_Membership_Op): In case of the membership test
	"Iface_CW_Typ in T'Class" we have nothing else to do in the frontend;
	the expander will generate the corresponding run-time check to evaluate
	the expression.
	(Resolve_Call): Check for legal type of procedure name or prefix that
	appears as a trigger in a triggering alternative.
	(Valid_Conversion): If expression is ambiguous and the context involves
	an extension of System, remove System.Address interpretations.
	(Resolve_Qualified_Expression): Reject the case of a specific-type
	qualification applied to a class-wide argument. Enhance comment
	to explain checking of Original_Node.
	(Resolve_Type_Conversion): The location of the error message was not
	general enough to handle the general case and hence it has been removed.
	In addition, this patch improves the text of the message.
	(Resolve_Type_Conversion): Add missing support for access to interface
	types.

	* sem_ch6.ads, sem_ch6.adb (Check_Conformance): In case of anonymous
	access types the null-exclusion and access-to-constant attributes must
	also match.
	(Analyze_Return_Statement): When the result type is an anonymous access
	type, apply a conversion of the return expression to the access type
	to ensure that appropriate accessibility checks are performed.
	(Analyze_Return_Type): For the case of an anonymous access result type,
	generate the Itype and set Is_Local_Anonymous_Access on the type.
	Add ??? placeholder for check to disallow returning a limited object
	in Ada 2005 unless it's an aggregate or a result of a function call.
	Change calls from Subtype_Mark to Result_Definition.
	(Analyze_Subprogram_Body): Change formal Subtype_Mark to
	Result_Definition in call to Make_Function_Specification.
	(Build_Body_To_Inline): Change Set_Subtype_Mark to
	Set_Result_Definition.
	(Make_Inequality_Operator): Change formal Subtype_Mark to
	Result_Definition in call to Make_Function_Specification.
	(Process_Formals): Create the new null-excluding itype if required.
	(New_Overloaded_Entity): For an entity overriding an interface primitive
	check if the entity also covers other abstract subprograms in the same
	scope. This is required to handle the general case, that is, overriding
	other interface primitives and overriding abstract subprograms inherited
	from some abstract ancestor type.
	(New_Overloaded_Entity): For an overriding entity that comes from
	source, note the operation that it overrides.
	(Check_Conformance, Type_Conformant): Addition of one new formal
	to skip controlling formals in the analysis. This is used to
	handle overloading of abstract interfaces.
	(Base_Types_Match): Add missing case for types imported from
	limited-with clauses
	(New_Overloaded_Entity): Add barrier to protect the use of

	V (Obj.F), the rewriting does not involve the indexed component, but
	only the selected component itself.
	Do not apply the transformation if the analyzed node is an actual of a
	call to another subprogram.
	(Complete_Object_Operation): Retain the entity of the
	dispatching operation in the selector of the rewritten node. The
	entity will be used in the expansion of dispatching selects.
	(Analyze_One_Call): Improve location of the error message associated
	with interface.
	(Analyze_Selected_Component): No need to resolve prefix when it is a
	function call, resolution is done when parent node is resolved, as
	usual.
	(Analyze_One_Call): Add a flag to suppress analysis of the first actual,
	when attempting to resolve a call transformed from its object notation.
	(Try_Object_Operation, Transform_Object_Operastion): Avoid makind copies
	of the argument list for each interpretation of the operation.
	(Try_Object_Operation): The designated type of an access parameter may
	be an incomplete type obtained through a limited_with clause, in which
	case the primitive operations of the type are retrieved from its full
