The DJGPP FAQ list (available as faq102.zip at the same place you get 
DJGPP) explains that DJGPP programs under OS/2 cannot spawn other DJGPP 
programs, and gcc.exe tries to do just that when it spawns the 
pre-processor, the compiler, the assembler and the linker passes.  You 
will have to use real-mode gcc.exe (get the file gcc263rm.zip from the 
DJGPP distribution) and real-mode Make program under OS/2.

The above is true unless you run OS/2 Warp, because in Warp these 
problems were reportedly corrected.  If you use Warp, please post more 
details about the crashes (stack traces would be nice) so that this 
problem could be investigated further.
