229 * implementation, is equipped with at least NT 3.51 stubs, dummy
230 * routines with same name, but which do nothing. Meaning that it's
231 * apparently sufficient to guard "vanilla" NT calls with GetVersion
232 * alone, while NT 4.0 and above interfaces ought to be linked with

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