That's the problem with blindly compiling Unix-born programs in DJGPP: 
they compile without a warning, then fail at runtime.  Some Unix calls 
cannot be easily implemented under DOS (some of them cannot be 
implemented at all), and so DJGPP has them as stubs which just fail.  
pipe() is one of these.  You should replace it with popen()/pclose() 
paradigm, or write your own code which redirects stdin/stdout and invokes 
a subsidiary program via spawn().
