It _is_ specific to the DJGPP port, and it's actually a feature (that
was there since Emacs 20).  The feature is designed to not clear the
screen if Emacs exits too quickly after the session begins.  That's
because the absolute majority of such quick exits are actually crashes
during startup, and so it is very important to leave the screen
contents intact, because they include vital clues to the reasons of
the crash.

If this feature somehow got in your way, please tell the details;
perhaps we could change it a bit to not interfere with whatever you
were doing.
