When a real-mode 16-bit app is spawned by DJGPP program, it works as 
usual in the lower 640KB (some 70-100KB of that is taken by the DPMI host 
and DOS memory that your DJGPP program uses).

The DJGPP FAQ list tells the story of the memory allocation when a DJGPP 
program spawns another DJGPP program.  Look in section 15.8 there.
