	* prj.ads, makeutl.adb, makeutl.ads (Queue.Insert): now also inserts
	the "roots" for a main.
	(Fill_From_Project): add support for aggregate projects. Main units
	in aggregated projects are now automatically added in the list of
	files to build (although this fails later on in gprbuild, because
	these files are not using the root proejct tree, so this needs
	further cleanup)
	* gcc-interface/Make-lang.in: Update dependencies.
