That's true, but DJGPP programs (being DOS programs, as far as Windows
is concerned), do not see %windir%, since Windows removes it from the
environment when it constructs the environment block for the DJGPP
program.

So the best method to distinguish NT/W2K/XP from DOS and 9X is by
looking at the %OS% environment variable.  See my other message in
this thread.
