I have a suggestion for you.  Try using EMX/GCC under OS/2 to compile the
DOS version.  The world of EMX is much closer in spirit to that of Unix than
is DJGPP.

The downside of this is that you have to run OS/2 to do the compilation.
I.e., EMX can produce executables that run under DOS, but the compiler
itself requires OS/2.
