250 * GetVersion() < 0x80000000. One can argue that in latter "or" case

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

349 Bits 0-2: status type: 0 = warning, 1 = success, 2 = error, 3 = info ...
350 The important thing to know is that odd numbers are considered
351 good, while even ones are considered errors.
352 Bits 3-15: actual status number
353 Bits 16-27: facility number. 0 is considered "unknown"
354 Bits 28-31: control bits. If bit 28 is set, the shell won't try to
355 output the message (which, for random codes, just looks ugly)
357 So, what we do here is to change 0 to 1 to get the default success status,
358 and everything else is shifted up to fit into the status number field, and
359 the status is tagged as an error, which I believe is what is wanted here.
