	* a-dirval.ads, a-dirval.adb, a-dirval-vms.adb, a-dirval-mingw.adb
	(Is_Path_Name_Case_Sensitive): New function

	* a-direct.adb (To_Lower_If_Case_Insensitive): New procedure
	(Base_Name, Simple_Name, Current_Directory, Compose,
	Containing_Directory, Full_Name): Call To_Lower_If_Case_Insensitive on
	the result.
