  Right, you need to include the command line switch so it compiles the
Ada you might expect, the one with overflow checking.  IMHO, you also
need to include the stuff to get a symbolic traceback on an unhandled
exception.  I would alternatively suggest Janus Ada for the quality
of its run-time error messages.  (www.rrsoftware.com)  That's the
compiler I learned Ada from.
