	where the controlling formal is of private class-wide type whose
	completion is a synchronized type can be converted into direct calls.

	* gnatcmd.adb (Check_Files): When all sources of the project are to be
	indicated to gnatcheck, gnatpp or gnatmetric, always specify the list
	of sources using -files=, so that the distinction can be made by the
	tool of a call with no source (to display the usage) from a call with
	a project file that contains no source.

	* exp_ch3.adb (Build_Array_Init_Proc): Do not build the init proc in
