	* err_vars.ads: Suppress range checks for a couple of assignments
	which otherwise cause validity checks with validity checking turned on.
	Update comments.

	* errout.adb (Error_Msg_Internal): Do not suppress warning messages.
	Make message unconditional if it is a warning.
	(Error_Msg_NEL): Always output warning messages.
	Suppress range checks for a couple of assignments which otherwise
	cause validity checks with validity checking turned on.

	* errout.ads (Message Insertion Characters): Document that '!' is
	implied by '?' in error messages.

	* gnat1drv.adb: (Bad_Body): Remove '!' in warning message.
	(Gnat1drv): Use a goto to end of main subprogram instead of
	Exit_Program (E_Success) so that finalization can occur normally.
