	* sem_ch13.adb (Analyze_Record_Representation_Clause): Alphabetize all
	local variables. Remove the general restriction which prohibits the

	(Analyze_Pragma): Unchecked_Union case: Propagate the Unchecked_Union
	type to all invocations of Check_Component and Check_Variant.
	(Check_Component): Add formal parameters UU_Typ and In_Variant_Part.
	Rewritten.  Add Ada 2012 check to detect improper use of formal
	private types and private extensions as component types of an
	Unchecked_Union declared inside a generic body.
	(Check_Variant): Add formal parameter UU_Typ. Propagate the
	Unchecked_Union type to all calls of Check_Component. Signal that the
	current component comes from the variant part of an Unchecked_Union
	type.

	* gnatcmd.adb (Check_Files): When looking for the .ci file for a
