I tried some stuff in Win2k.  What I found was a little puzzling...

It only seems to crash after gcc has compiled something.
I tried it with SetEdit as well.  I told SetEdit to run "gcc a.cc -o a.exe".
It ran fine, but then crashed when I hit a key (any key).
I told SetEdit to run "ls".  Proper output was printed, and that did not crash
anything.
I told SetEdit to run "gcc".  The 'no input files' message was printed and i
did not crash.
I tried running bash, and then ls and other stuff from there.  Nothing caused
a crash.

Maybe it had to do with whether the sub-djgpp program opens files... I'll
check that later...
