You can call OS_Exit or OS_Abort in GNAT.OS_Lib.  Look at the comments
to see misc subtle issues.

Or you can use pragma Import to interface directly to the OS
exit routine, if you're on an OS that has such (most do).

Or you can raise an exception, handle it at the bottom of the main
procedure, and then just drop off the end.  But you need to make
sure any tasks will terminate -- the main procedure will wait for
that, and if they never terminate, it will wait forever.

Or you can abort the environment task.
