2007-04-06  Vincent Celier  <celier@adacore.com>

	* mlib.adb (Building_Library): Only output "building a library..." in
	verbose mode

	* mlib-prj.adb (Build_Library): Only output lists of object and ALI
	files in verbose mode.

	* mlib-utl.adb (Ar): Only output the first object files when not in
	verbose mode.
	(Gcc): Do not display all the object files if not in verbose mode, only
	the first one.
