OK, sorry.  This work was done in late spring 1996.  I've forgotten a lot
of the filenames.  I think that my last message should make clear what was
necessary.

As I wrote before, we set up 'mmap-capable' DJGPP as a separate machine
target.  That's enough to have djgpp-gcc pass ld a different set of
options; ld itself didn't need a recompile, IIRC.

I don't remember, sorry.  What version was current in May 1996?

I also don't know if CMU has tracked subsequent DJGPP releases or not.
