Hi,
could you tell me how simply and reliable runtime check if my DJGPP
prog is running under WinNT-XP dos box? I need to exclude some code
from execution under NT.

I used simply checking by getenv("SystemRoot"), where SystemRoot env.
variable is always set on NT systems but getenv is case sensitive so
when I met "SYSTEMROOT" it fails to detect NT and crashed.  I can't
compare every case combination. Other idea?
