The cygwin32-mount.el that I found in (one of) the mailing lists helps Emacs
convert Cygwin mount points to Windows directories on filename expansion.
I've done a little hacking on it in that it was not picking up the right
mount point for the filename expansion in some cases. Basically, it was
picking a shorter name (ie. "/usr" instead of "/usr/emacs"). A simple
reverse sort on the mount point list (to push the bigger names to the top)
fixed the problem.
The new cygwin32-mount.el is attached. Simply install it in your lisp path,
byte compile it, and load it in your .emacs.
My free software work for the day... :-)
