2006-10-31  Vincent Celier  <celier@adacore.com>

	* mlib-utl.adb (Initialized): Remove, no longer used
	(Initialize): Remove, no longer used
	(Ar): If Ar_Exec is null, get the location of the archive builder and,
	if there is one, the archive indexer. Fail if the archive builder cannot
	be found.
	(Gcc): If the driver path is unknown, get it. Fail if the driver cannot
	be found.
