	* prj-proc.adb, prj-attr.adb, prj-attr.ads (Get_Attribute_Index): do
	not systematically lower case attribute indexes that contain no "."
	Fix definition of several Naming attributes, which take
	a unit name as index and therefore should be case insensitive.
	Minor refactoring (reduce length of variable names).

	* makeutl.adb, makeutl.ads (Get_Switches): new subprogram.
