	(Complete_Object_Operation): Retain the entity of the

	(Analyze_One_Call): Improve location of the error message associated

	* sem_ch3.ads, sem_ch3.adb (Analyze_Object_Declaration): Go to the
	underlying type
	to check if a type is Constrained in cases related to code generation
	(rather than semantic checking) since otherwise we do not generate
	similar code for mutable private types depending if their
	discriminants are visible or not.
	(Check_Abstract_Overriding): Do not complain about failure to override
	the primitive operations used in dispatching selects since they will
	always be overriden at the freeze point of the type.
	(Access_Definition): Separate out handling for resetting the scope
	of an anonymous access function result type. Retrieve the scope
	of the associated function rather than using Current_Scope, which
	does not have a consistent value (depends on whether we're in the
	middle of analyzing formal parameters). Add ??? comment about
	finding a cleaner way to handle the special cases of scope setting.
	(Process_Incomplete_Dependents): A protected operation is never a
	dispatching operation (only its wrapper may be).
	(Build_Derived_Record_Type): In case of tagged private types that
	implement interfaces add derivation of predefined primitive
	operations.
	(Derive_Subprograms): Replace the Is_Interface_Derivation parameter
	by two parameters that are used in case of derivation from abstract
	interface types: No_Predefined_Prims is used to avoid the derivation
	of predefined primitives from the interface, and Predefined
	Prims_Only is used to complete the derivation predefined primitives
	in case of private tagged types implementing interfaces.
	Fix typo in comments
	(Find_Interface_In_Descendant): Protect the frontend against
	wrong code with large circularity chains.
	(Is_Private_Overriding): Add support for entities overriding interface
	subprograms. The test failed because Entities associated with overriden
	interface subprograms are always marked as hidden (and used to build
	the secondary dispatch table); in this case the overriden entity is
	available through the field abstract_interface_alias (cf. override_
	dispatching_operation)
	(Access_Definition): Set the scope of the type to Current_Scope for the
	case of a function with an anonymous access result type.
	(Access_Subprogram_Declaration): Handle creation of the type entity for
