  	(Original_Access_Type): Remove, not needed.
  	(Root_Type): Handle properly subtypes of class-wide-types.
  	Update comments.
  
  	* sem_ch4.adb (Analyze_Explicit_Dereference): Add support for
  	class-wide types visible through limited-with clauses.
  	(Try_Primitive_Operation): When examining all primitive operations of a
  	tagged type, do not consider subprograms labeled as hidden unless they
  	belong to a private generic type with a tagged parent.
  	(Try_Object_Operation): Extensive rewriting, to handle properly various
  	overloading cases, when several ancestors may have class-wide operations
  	that are possible candidates, and when the overloaded functions return
  	array types and have defaulted parameters so that the call may be
  	interpreted as an indexing.
  	(Analyze_Allocator): Remove Mark_Allocator and its invocation.
  	(Process_Function_Call): use Next, rather than Next_Actual, to analyze
  	successive actuals before analyzing the call itself.
  	(Try_Primitive_Operation): A primitive operation is compatible with the
  	prefix if the prefix has a synchronized type and the type of the formal
  	is its corresponding record, as can be the case when the primitive
  	operation is declared outside of the body of the type.
  	(Traverse_Homonyms): New subprocedure of Try_Class_Wide_Operation, to
  	perform homonym traversal, looking for class-wide operation matches
  	(formerly done in statements of Try_Class_Wide_Operation). Matches on
  	access parameters are now restricted to anonymous access types.
  	(Mark_Allocator): An allocator with a discriminant association parent is
  	a coextension.
  	(Try_One_Prefix_Interpretation): If the type of the object is
  	incomplete, as can be happen when it is a limited view obtained through
  	a limited_with_clause, the selected component is not part of a prefixed
  	call.
  	(Complete_Object_Operation): Diagnose properly an object that is not
  	aliased when the corresponding controlling formal is an access
  	parameter.
  	(Try_Primitive_Operation, Try_Class_Wide_Operation): Diagnose properly
  	ambiguous calls in prefixed notation, where two primitives differ only
  	in that the controlling argument of one is an access parameter.
  
  	* sem_ch6.adb (Has_Single_Return): Add guard in code that determines
  	whether a function that returns an unconstrained type can be inlined.
  	(Process_Formals): Diagnose properly the illegal use of an incomplete
  	type in the profile of an access_to_subprogram declaration.
  	(Check_Synchronized_Overriding): Nothing check for concurrent types, the
  	operations are attached to the corresponding record.
  	(Analyze_Subprogram_Specification): Add variables Formal and Formal_Typ.
  	When processing a primitive of a concurrent type which implements an
  	interface change the type of all controlling formals to that of the
  	corresponding record type.
  	(Check_Synchronized_Overriding): Relax the conditional logic when trying
  	to determine the tagged type to which a primitive belongs.
  	(Check_Conventions): Capture condition to ignore a primitive operation
  	(which is shared between the loop in Check_Conventions and the one in
  	Check_Convention) in a new local function Skip_Check.
  	(Check_Convention): Rename Prim_Op to Second_Prim_Op to avoid possible
  	confusion with Check_Conventions' own Prim_Op local variable.
  	(Create_Extra_Formals): Test for a tagged result type rather than a
  	controlling result when determining whether to add a BIP_Alloc_Form
  	formal and a BIP_Final_List formal to the function.
  	(Check_Conformance); For parameters that are anonymous access types,
  	subtype conformance requires that the not null and the constant
  	indicators must match
  	(Check_Synchronized_Overriding): New parameter Formal_Typ. Add machinery
  	to retrieve the appropriate type when processing a concurrent type
  	declared within a generic. Minor comment reformatting. Change invocation
  	of Overrides_Synchronized_Primitive to Find_Overridden_Synchronized_Pri-
  	mitive.
  	(Analyze_Subprogram_Body): If the return type of a function is an
  	anonymous access to the limited view of a class-wide type, and the
  	non-limited view of the type is available, update the type of the
  	function so that code can be generated.
  	(Process_Formals): In case of access-subtype itype whose designated
  	type is also an itype (situation that happens now with access to
  	subprograms) we mark the access-type itype with the Has_Delayed_Freeze
  	attribute to avoid backend problems.
  	(Check_Return_Subtype_Indication): Replace R_Type with R_Stm_Type in
  	init of R_Stm_Type_Is_Anon_Access. Also check that base types of the
  	anonymous types' designated types are same before testing
  	Subtypes_Statically_Match.
  	(Create_Extra_Formals): Test for a named access parameter that is a
  	controlling formal as an additional condition for adding an
  	accessibility level formal. This can occur in the subp type created for
  	dispatching calls in Expand_Dispatching_Call, and allows calling
  	Create_Extra_Formals from that procedure rather than special-casing the
  	extra formals there.
  	(Create_Extra_Formals): Add BIP_Alloc_Form and BIP_Final_List formals
  	when the function has a controlling result.
  	(Check_Returns): Add much more knowledge of the optimization of local
  	raise statements to gotos, to retain proper warnings in this case.
  	(Check_Statement_Sequence): Ignore N_Push_xxx_Label and N_Pop_xxx_Label
  	nodes when looking for last statement.
  
  	* sem_type.ads, sem_type.adb (Specific_Type): Add support for
  	class-wide types visible through limited with clauses.
  	(Add_One_Interp): If the operands are anonymous access types, the
  	predefined operator on universal_access is immediately visibles
  	(Find_Unique_Type): Handle anonymous access to subprogram types just as
  	other anonymous access types.
  	(Disambiguate): Take into account CIL convention.
  	(Interface_Present_In_Ancestor): Add support for class-wide interfaces.
