Either <go32.h> or <stdio.h> include <sys/version.h>, where it is
defined.  if you don't happen to include either of these, you won't
get it defined.

You can't.  And, in fact, shouldn't.  The flags tell you what it was
compiled *for*, not what it was compiled *on*.  You can try using
uname() to figure out what machine you're *running on* if that's what
you're really looking for.
