	* exp_aggr.ads,

	an actual for an access parameter.
	(Is_Static_Dispatch_Table_Aggregate): Handle aggregates initializing

	* sem_util.ads, sem_util.adb: (Is_Variable): Add defense against junk
	parameter
	(Is_Synchronized_Tagged_Type): New subprogram that returns true
	in case of synchronized tagged types (AARM 3.9.4 (6/2)).
	(Safe_To_Capture_Value): Can now return True for constants, even if Cond
	is set to False. Improves handling of Known_[Not_]Null.
	(Wrong_Type): Special case address arithmetic attempt
	(Collect_Abstract_Interfaces): Add new formal to allow collecting
	abstract interfaces just using the partial view of private types.
	(Has_Abstract_Interfaces): Add new formal to allow checking types
	covering interfaces using the partial view of private types.
	(Is_Fully_Initialized_Type): Special VM case for uTag component. This
	component still needs to be defined in this case, but is never
	initialized as VMs are using other dispatching mechanisms.
	(Abstract_Interface_List): For a protected type, use base type to get
	proper declaration.

	(Build_Derived_Type): For the completion of a private type declaration
	with a derived type declaration, chain the parent type's representation
	items to the last representation item of the derived type (not the
	first one) if they are not present already.
	(Analyze_Object_Declaration, Constant_Redeclaration): Allow incomplete
	object declaration of forward references to tags.
	(Access_Subprogram_Declaration): In Ada2005, anonymous access to
	subprogram types can appear as access discriminants of synchronized
	types.
	(OK_For_Limited_Init_In_05): The initialization is legal is it is a call
	given in prefixed form as a selected component.
