Unlike Borland, DJGPP line-buffers stdio. Add fflush(stdout) after the
printf's in the loop (or a \n at the end of the line) and all should work.

printf (args...);  fflush(stdout); 
should update immediately.

There's a CRT-startup-flag thing for that I think. Check the docs or wait
for a followup by someone more knowledgeable than I. (Eli?)

Well, there must be a mistake or typo here. There is no code in DJGPP that
looks for LFN set to "3Dy". It should be just set LFN=y. I am not aware of
any such switch, nor do I know there isn't one, again check the dox or
wait for followups.
