	* sem_ch7.adb (Check_Anonymous_Access_Types): New procedure, subsidiary
	of Analyze_Package_Body, to create Itype references for anonymous
	access types created in the package declaration, whose designated types
	may have only a limited view.
	(Analyze_Package_Specification): For the private part of a nested
	package, install private_with_clauses of enclosing compilation unit if
	we are in its visible part.
	(Declare_Inherited_Private_Subprograms): Complete barrier
	to ensure that the primitive operation has an alias to some parent
	primitive. This is now required because, after the changes done for the
	implementation of abstract interfaces, the contents of the list of
	primitives has entities whose alias attribute references entities of
	such list of primitives.
	(Analyze_Package_Specification): Simplify code that handles parent units
	of instances and formal packages.
	(Uninstall_Declarations): Check the convention consistency among
	primitive overriding operations of a tagged record type.
