I would hope that on VMS, exit(0) maps to status code 1 (success,
no error; it is possible on VMS to have failures without errors
and successes with errors), and that anything else maps to a status
that indicates an `unspecified error'.  VMS C should provide another
`exit'-like routine that actually just passes its argument on to
the termination system call.  Use of the *latter* routine would
be unportable, though preferred for VMS system programs.

(It might be feasible to have exit() map values from <sysexits.h>
to VMS status codes, I suppose.)
