When building gcc, the file config/i386/go32.h has a section that
looks like this

#ifdef CPP_PREDEFINES
#undef CPP_PREDEFINES
#endif
#define CPP_PREDEFINES "-Dunix -Di386 -DGO32 -DMSDOS \
 yada yada yada

My version (egcs based) does not include a -DDJGPP here.  This can be
overridden
in the specs file for the compiler, which is in you lib/specs dir.  To see
if your version of
the compiler itself has it compile with '-dumpspecs'.  To undefine it you
will probably need to
overwrite the specs file.
