233 * implementation, is equipped with at least NT 3.51 stubs, dummy
234 * routines with same name, but which do nothing. Meaning that it's
235 * apparently sufficient to guard "vanilla" NT calls with GetVersion

375 We need to do this since VMS has the following coding on status codes:
377 Bits 0-2: status type: 0 = warning, 1 = success, 2 = error, 3 = info ...
378 The important thing to know is that odd numbers are considered
379 good, while even ones are considered errors.
380 Bits 3-15: actual status number
381 Bits 16-27: facility number. 0 is considered "unknown"
382 Bits 28-31: control bits. If bit 28 is set, the shell won't try to
383 output the message (which, for random codes, just looks ugly)
385 So, what we do here is to change 0 to 1 to get the default success status,
386 and everything else is shifted up to fit into the status number field, and
387 the status is tagged as an error, which I believe is what is wanted here.
