	(Parse_Single_Project): Set the parent project for child projects
	(Create_Virtual_Extending_Project): Register project with no qualifier
	(Parse_Single_Project): Allow an abstract project to be extend several
	times. Do not allow an abstract project to extend a non abstract

	(Print): Take into account the full associative array attribute
	declarations.

	* prj-proc.adb: Use functions Present and No throughout
	(Expression): Call itself with the same From_Project_Node for the
	default value of an external reference.

	* prj-strt.adb: Use functions Present and No throughout
	(Parse_Variable_Reference): If a variable is specified as a simple name
	and is not found in the current project, look for it also in the
	ancestors of the project.

	* prj-tree.ads, prj-tree.adb (Present): New function
	(No): New function
	Use functions Present and No throughout
	(Parent_Project_Of): New function
	(Set_Parent_Project_Of): New procedure

	* snames.ads, snames.adb: 
	Add new standard names Object_Generated and Objects_Linked
