Recently there have been reports of djgpp programs
that "just hang". I found a way to duplicate this
behavior by undefining the DJGPP environment variable.

Try this out with DOS and CWSDPMI (not a Windows dos box).
I have a full 2.81 distribution.

     Nothing appears to happen, but paging will start
     in about 10 seconds. Watch your disk light.

     You will get a SIGABRT message.

The swap file C:\CWSDPMI.SWP contains many repetitions of
the string "$DJDIR/lib/gcc-lib/". Something is getting into
a loop and filling up memory.
