	* gnatls.adb: Take into account GPR_PROJECT_PATH, when it is defined,
	instead of ADA_PROJECT_PATH, for the project path.
	(Gnatls): When displaying the project path directories, use host dir
	specs.

	* prj-ext.adb (Prj.Ext elaboration): On VMS, only expand relative path
	names in the project path, as absolute paths may correspond to
	multi-valued VMS logical names.
