	* prj.ads (For_Every_Project_Imported): Add In_Aggregate_Lib
	parameter to generic formal procedure.
	* prj.adb (For_Every_Project_Imported): Update accordingly.
	(Recursive_Check): Likewise. Do not parse imported project for
	aggregate library. This is needed as the imported projects are
	there just to handle dependencies.
	(Look_For_Sources): Likewise.
	(Recursive_Add): Likewise.
	* prj-env.adb, prj-conf.adb, makeutl.adb, gnatcmd.adb:
	Add In_Aggregate_Lib parameter to routines used with
	For_Every_Project_Imported generic procedure.
	* prj-nmsc.adb (Tree_Processing_Data): Add In_Aggregate_Lib field.
	(Check): Move where it is used. Fix implementation
	to not check libraries that are inside aggregate libraries.
	(Recursive_Check): Add In_Aggregate_Lib parameter.

	* sem_ch7.adb (Analyze_Package_Body, Has_Referencer): A generic
	package is a referencer regardless of whether there is a
	subsequent subprogram with an Inline pragma.
