No you are not missing anything.  I will try HAVE_DOS_PATHS.  If that
works, and there is agreement with the cygwin folks, I would like
to have the build process changed gnu make so that the default build
on cygwin defines HAVE_DOS_PATHS.  What process would I have to follow
to have that change made.
