Standard COFF as far as I can see.  I made it work by

#include <../go32/gotypes.h>
#include <../go32/ed/coff.h>
#define n_type e_type
/* and one more #define of the same kind */
struct aouthdr {
  /* copy from ../go32/aout.h which for some reason only defines the 
     typedef AOUTHDR type */
}

This works fine except that I cannot debug the dumped Emacs.  If you find out
why, let me know.
