Thanks for the info!

But still I don't know how to get the system time in OS/2 or non-DPMI DOS
(I was using the DPMI call only to call a DOS int, since I'm not sure if
calling int 21 directly is OK) -- or some other way to init random; AFAICS,
the system unit v1.00 doesn't do any random initialization at all...
Besides, I couldn't test it with EMX, anyway. So I won't change it now.
If someone who has EMX can change it, please do so and post the result here.
