Well, that's okay, since I do.  C99 specifies that snprintf() returns the
number of bytes that would have been necessary, if the buffer had been big
enough.  Meaning that, unsurprisingly, Microsoft is wrong and behind the
standards curve (yet again).  That's certainly not enough to discourage me
from using the standard, and it shouldn't be for anyone else.  There are
already free, correct implementations of snprintf() available that would
make a fine interim solution for such unfortunate souls as must rely on
Microsoft's timeliness.
