255 * Most notably we ought to check for availability of each specific
256 * routine with GetProcAddress() and/or guard NT-specific calls with
257 * GetVersion() < 0x80000000. One can argue that in latter "or" case
258 * we ought to /DELAYLOAD some .DLLs in order to protect ourselves

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

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