    We need to do this since VMS has the following coding on status codes:

    Bits 0-2: status type: 0 = warning, 1 = success, 2 = error, 3 = info ...
              The important thing to know is that odd numbers are considered
              good, while even ones are considered errors.
    Bits 3-15: actual status number
    Bits 16-27: facility number.  0 is considered "unknown"
    Bits 28-31: control bits.  If bit 28 is set, the shell won't try to
                output the message (which, for random codes, just looks ugly)

    So, what we do here is to change 0 to 1 to get the default success status,
    and everything else is shifted up to fit into the status number field, and
    the status is tagged as an error, which is what is wanted here.

    Finally, we add the VMS C facility code 0x35a000, because there are some
    programs, such as Perl, that will reinterpret the code back to something
    POSIX.  'man perlvms' explains it further.

    NOTE: the perlvms manual wants to turn all codes 2 to 255 into success
    codes (status type = 1).  I couldn't disagree more.  Fortunately, the
    status type doesn't seem to bother Perl.
