	* par-ch3.adb (P_Range_Or_Subtype_Mark): Check for bad parentheses
	(P_Type_Declaration): Remove barrier against the reserved word "limited"
	after "abstract" to give support to the new syntax of AARM 3.4 (2/2).
	(P_Type_Declaration): Minor code cleanup. Add support for synchronized
	private extensions.
	(P_Type_Declaration): Add the new actual Abstract_Present to every call
	to P_Interface_Type_Definition.
	(P_Interface_Type_Definition): Addition of one formal to report an error
	if the reserved word abstract has been previously found.

	object renaming declaration with an access definition or subtype mark
	with a possible null exclusion.
