DJGPP eats up about 130K of *conventional* memory for each DJGPP-compiled
program.  The extended and virtual memory are only used for the protected-
mode code of the program you wrote, but go32 (the extender) runs as DOS
program, and as such uses conventional memory below 640K.

This is very low number.  Try to nake it larger by moving things to the
upper memory (with Memmaker or QEMM's Optimize).  You should be able to
invoke at least 2 or even 3 DJGPP programs one from inside the other,
otherwise you won't be able to even run Make.
