Could you please be more specific?  Where in ELisp will Cygwin paths
be inserted?

Is this change only for the unexec phase, or for the entire Emacs
operation?  If the former, you could use O_BINARY in unexw32.c and be
done with it.  If the latter (which I suspect is the case), emacs.c
already has similar code fragments for other DOS/Windows ports, so I
think the MinGW port should also use it (I actually thought it already
did, so I wonder how come this was a problem in your case).
