I don't think DJGPP should cause problems if they're easy to deal with
in a reasonably correct way.  However, in this case, I prefer that
DJGPP headers protect themselves with #undef rather than #ifdef, so
that we also protect ourselves from incompatible definitions (if any).
Thus (to paraphrase) we should have:

#undef NULL
#define NULL 0
