* 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.
