MASM can produce COFF-format .OBJ files which can be easily linked to
DJGPP object files. You have to give the /coff switch to MASM and use a
calling convention understood by DJGPP (C calling convention I think).
You also have to deal with the underbars at the beginning of function
names. But after that, it works.
