	    Bob Duff  <duff@adacore.com>
	    Gary Dismukes  <dismukes@adacore.com>

	* errout.adb (Unwind_Internal_Type): Use predicate
	Is_Access__Protected_Subprogram_Type.

	* freeze.adb (Size_Known): Use First/Next_Component_Or_Discriminant
	(Freeze_Entity, packed array case): Do not override explicitly set
	alignment and size clauses.
	(Freeze_Entity):  An entity declared in an outer scope can be frozen if
	the enclosing subprogram is a child unit body that acts as a spec.
	(Freeze_Entity): Use new predicate Is_Access_Protected_Subprogram_Type.
	(Freeze_Record_Type): New Ada 2005 processing for reverse bit order
	Remove all code for DSP option

	* layout.adb (Layout_Record_Type): Use First/
	Next_Component_Or_Discriminant
	(Layout_Type): Use new predicate Is_Access_Protected_Subprogram_Type,
	to handle properly the anonymous access case.

	* sem_attr.adb (Build_Access_Object_Type): Use E_Access_Attribute_Type
	for all access attributes, because overload resolution should work the
	same for 'Access, 'Unchecked_Access, and 'Unrestricted_Access. This
	causes the error message for the ambiguous "X'Access = Y'Access" and
	"X'Unrestricted_Access = Y'Access" and so forth to match.
	(Resolve_Attribute, case 'Access): Remove use of Original_Access_Type,
	now that anonymous access to protected operations have their own kind.
	(Resolve_Attribute): In case of dispatching call check the violation of
	restriction No_Dispatching_Calls.
	(Check_Array_Type): Check new -gnatyA array index style option

	* sem_ch3.ads, sem_ch3.adb (Derived_Type_Declaration): Reject an
	attempt to derive from a synchronized tagged type.
	(Analyze_Type_Declaration): If there is a incomplete tagged view of the
	type, inherit the class-wide type already created, because it may
	already have been used in a self-referential anonymous access component.
	(Mentions_T): Recognize self-referential anonymous access components
	that use (a subtype of) the class-wide type of the enclosing type.
	(Build_Derived_Record_Type): Add earlier setting of Is_Tagged_Type. Pass
	Derived_Type for Prev formal on call to
	Check_Anonymous_Access_Components rather than Empty.
	(Make_Incomplete_Type_Declaration): Add test for case where the type has
	a record extension in deciding whether to create a class-wide type,
	rather than just checking Tagged_Present.
	(Replace_Anonymous_Access_To_Protected_Subprogram): Procedure applies
	to stand-alone object declarations as well as component declarations.
	(Array_Type_Declaration): Initialize Packed_Array_Type to Empty, to
	prevent accidental overwriting when enclosing package appears in
	a limited_with_clause.
	(Array_Type_Declaration): If the component type is an anonymous access,
	the associated_node for the itype is the type declaration itself.
	(Add_Interface_Tag_Components): Modified to support concurrent
	types with abstract interfaces.
	(Check_Abstract_Interfaces): New subprogram that verifies the ARM
	rules 3.9.4 (15/2), 9.1 (9.d/2) and 9.4 (11.d/2).
	(Build_Derived_Record_Type): Add call to Analyze_Interface_Declaration
	to complete the decoration of synchronized interface types. Add also
	a call to Check_Abstract_Interfaces to verify the ARM rules.
	(Derive_Interface_Subprograms): Modified to support concurrent types
	with abstract interfaces.
	(Analyze_Subtype_Indication): Resolve the range with the given subtype
	mark, rather than delaying the full resolution depending on context.
	(Analyze_Component_Declaration,Analyze_Interface_Declaration,
	Analyze_Object_Declaration,Analyze_Subtype_Declaration,
	Array_Type_Declaration,Build_Derived_Record_Type,
	Build_Discriminated_Subtype,Check_Abstract_Overriding,Check_Completion,
	Derive_Interface_Subprograms,Derive_Subprogram,Make_Class_Wide_Type,
	Process_Full_View,Record_Type_Declaration): Split Is_Abstract flag into
	Is_Abstract_Subprogram and Is_Abstract_Type. Make sure these are
	called only when appropriate.
	(Copy_And_Swap): Copy Has_Unreferenced_Objects flag from full type
	to private type.
	(Analyze_Subtype_Declaration): For an access subtype declaration, create
	an itype reference for the anonymous designated subtype, to prevent
	scope anonmalies in gigi.
	(Build_Itype_Reference): New utility, to simplify construction of such
	references.
