First guess: 
 The video memory (if any) is not were DJGPP supposes it
 to be.
Maybe start with a program that does nothing at all, 
simply return 0.
Then, do some integer stuff, maybe try writing to a file. 
Also, it could be you need the NPX emulator. If I remember
correctly, the startup code does a few things to check
if a x87 is available, and otherwise tries to load
the emulator. But as I do not have a machine without
NPX here, I would not really believe me ;-)
