Rsync link-dest not working for a host with the most recent rsync/cygwin 1.7

It appears something about the about rsync or the 1.7 version of
cygwin is preventing the --link-destination function of rsync from
working. Files that have not been changed at all should be linked
together. On the hosts still running a cygwin 1.5 version of rsync
the link-destination seems to work exactly as I expect it to.
I am using dirvish (http://www.dirvish.org/) on a Linux box (deb
5.0.3) to backup some of the data on windows boxes in the network. I
have the cygwin+rsync setup in daemon mode on the servers. I recently
upgraded a couple of the boxes to the latest cygwin 1.7. On the
systems with cygwin 1.5 files are occasionally missed because of the
path length limitations so I really want to get a cygwin 1.7 setup
working.
This is the command that is being issued by dirvish to perform the backup.
rsync -vrltH --delete -pgo --stats -z -D --numeric-ids --timeout=300
--exclude-from=/srv/dirvish/srv-01/2009101610/exclude
--link-dest=/srv/dirvish/srv-01/2009101420/tree 10.2.35.241::data/
/srv/dirvish/srv-01/2009101610/tree
Here is the checksums and the output of stat of two files on my Linux
box that I should have been linked together. No changes where made to
this file on the windows box between the first and second backups.

I have posted the output of 'cygcheck -s -v -r' here
(http://pastebin.com/m68d01c02).
I would appreciate some help getting the --list-dest to work properly.
If you have some ideas please share. If you need more information to
help diagnose or find a solution please ask.
Thanks,
Chris Francy
