	full view to partial view, to simplify handling in back-end.

	* sprint.adb: Print interface lists where needed: derived types,
	protected types, task types.
	output "is null" for null procedures. Part of implementation of

	* sem_cat.adb (Validate_Access_Type_Declaration): Implement AI-366
	relaxation of rules for access types in pure, shared passive partitions.

	* exp_strm.adb (Build_Mutable_Record_Read_Procedure): Reorganize to
	first read discriminants into temporary objects, performing checks on
	the read values, then possibly performing discriminant checks on the
	actual (if it is constrained), and only finally reading the components
	into a constrained temporary object.
	(Build_Elementary_Input_Call): Adjust the specific circuitry for the
	case of reading discriminants of a mutable record type to recognize
	the new form of the code generated by
	Build_Mutable_Record_Read_Procedure.

	* exp_tss.ads, exp_tss.adb (Make_Init_Proc_Name): Reimplement in terms
	of a simple call to Make_TSS_Name.
	(Make_TSS_Name_Local): Add the TSS name as the last thing in the name
	buffer, in order for Is_TSS to work correctly on local TSS names.

	* sem_attr.ads, sem_attr.adb (Resolve_Attribute, case 'Access): Use flag
	Is_Local_Anonymous_Access to check legaliy of attributes in the
	context of  access components and stand-alone access objects.
	(Stream_Attribute_Available): In Ada 95 mode, a stream attribute is
	treated as available for a limited private type if there is an
	attribute_definition_clause that applies to its full view, but not in
	other cases where the attribute is available for the full view
	(specifically, the sole fact that the full view is non-limited does not
	make the attribute available for the partial view).
	(Build_Access_Subprogram_Type): Diagnose attempt to apply 'access to a
	non-overloaded intrinsic subprogram.
	(Check_Stream_Attribute): Reject an attribute reference for an
	unavailable stream attribute even if the prefix is not a limited type
	(case of a 'Input attribute reference for an abstract, non-classwide
	type)
	(Stream_Attribute_Available): New function to determine whether a stream
	attribute is available at a place.
	(Check_Attribute): Use Stream_Attribute_Available instead of just
	testing for TSS presence on the implementation base type.
	(Analyze_Attribute): Modified to give support to task interfaces.
	(Analyze_Access_Attribute): Add error check for use of an Access (or
	Unrestricted_Access) attribute with a subprogram marked as
	Inline_Always.
	(Analyze_Attribute, case Attribute_Address): Add error check for use of
	an Address attribute with a subprogram marked as Inline_Always.
	Update Eval_Attribute to handle new value of Width from AI-395

	* sem_ch13.adb (Analyze_Stream_TSS_Definition): New subprogram.
	(Analyze_Attribute_Definition_Clause, cases Input, Output, Read, Write):
	Factor common code across the stream-oriented attribute circcuits into
	a new subprogram, Analyze_Stream_TSS_Definition. The new uniform
	processing is functionally identical to the previous duplicated one,
	except that an expression that denotes an abstract subprogram will now
	be rejected, as mandated by AI-195 item 5.

	* sem_util.ads, sem_util.adb (Type_Access_Level): Use flag
	Is_Local_Anonymous_Access to apply accessibility checks to access
	components and stand-alone access objects.
	(Has_Discriminant_Dependent_Constraint): Moved to spec for use
	elsewhere.
	(Is_Potentially_Persistent_Type): New function
	(Is_Dependent_Component_Of_Mutable_Object): If the enclosing object is
	a heap-object whose type has a constrained partial view, the object is
	unconstrained and the component may depend on a discriminant, making its
	renaming illegal.

	* sinfo.ads, sinfo.adb
	(Must_Not_Override): Flag applicable to N_Entry_Declaration.
	(Must_Override): Flag applicable to N_Entry_Declaration.
	Indicate that interface_list can appear in single task and single
	protected declarations.
	Replace Is_Overriding and Not_Overriding with Must_Override and
	Must_Not_Override, to better express intent of AI.
	Is_Overriding, Not_Overriding: Ada2005 flags that indicate the presence
	of an overriding indicator in a subprogram or instance.
	Ada 2005 (AI-248) Null_Present can appear in a procedure specification.
	Add the overriding indicator [[not] overriding] construct to the
	following grammar productions:
	 ENTRY_DECLARATION
	 GENERIC_INSTANTIATION
	 SUBPROGRAM_SPECIFICATION

	* par-ch10.adb (P_Compilation_Unit): Subprogram declaration or body
	can start with an overriding indicator.

	* par-ch6.adb (P_Subprogram): Recognize overriding indicator, and set
	flags accordingly on subrogram specifications or instances.

	* sem_ch8.adb:
	(Analyze_Subprogram_Renaming): For a renaming_as_body, verify that the
	overriding_indicator, if present, is consistent with status of spec.
	Improve error message for null-excluding checks on controlling access
	parameters.
	(Check_In_Previous_With_Clause): Protect the frontend against
	previously reported critical errors in the context clauses.
	Save and restore Ada_Version_Explicit, for implementation of AI-362
	(Analyze_Subprogram_Renaming): If the new entity is a dispatching
	operation verify that controlling formals of the renamed entity that
	are access parameters are explicitly non-null.
	(Find_Expanded_Name): Improve error message when prefix is an illegal
	reference to a private child unit.

	* exp_imgv.adb, s-imgwch.ads, s-imgwch.adb, s-valwch.adb,
	s-valwch.ads, s-widwch.adb, s-widwch.ads, s-wwdcha.adb, s-wwdwch.adb:
	Rewrite to correspond to new wide character names in AI-395

        * par-ch12.adb (P_Formal_Subprogram_Declaration): Recognize null
        default procedures.
