Unfortunately, Microsoft's COFF is not the same as DJGPP's COFF,
so there's no hope of this working.  If you want to use assembly
language with DJGPP you really have to use either NASM or Gas.

Converting to NASM syntax would probably be easier than converting
to Gas (AT&T) syntax.

Alternatively, it should be possible to write an MS-COFF-to-DJGPP-COFF
converter, especially as the two formats are so similar.  Obviously
this would not be a particularly trivial undertaking, but it might be
easier than converting all your asm source code (depending on how much
there is and how un-NASM-like your MASM coding style is).  See the
comments in the file outcoff.c in the NASM sources for a list of the
differences between the two types of COFF.
