/usr/local is a common subtree on Linux systems, common enough that
setup makes sure it exists by creating it.  Setup, though, doesn't
know about all the variations of symlinks that Cygwin itself does
so its pretty heavy-handed when it comes to symlinks that get in
its way.  As a work-around, you could script setup so that it
recreates the symlink you want with each run.  You could even make
your own "mirror" which provides a package that contains only a
postinstall script that does this, so that anytime you run setup,
you could install or reinstall this package from your own mirror
to make this more generic and integrated.  Another alternative
is to take a look at setup's source and see if you can create a
patch to handle this better.  You can probably think up some
other possibilities for a solution that you like even better. :-)
