This fixed the special mode bits.  They are kept intact now.  It also fixed
another issue.  Previously files with changes in ACLs alone would not be
synced.  Now the ACL only changes are being rsynced and uodated on the
destination.

1) I grabbed the nightly build and compiled it in Cygwin.  It works great
for local Cygwin rsyncs (i.e. local folder to local folder).  

2) I tried doing rsyncs to a linux server running 2.6.6 (my ultimate goal
here)

Linux rsync version:

# rsync --version
rsync  version 2.6.6  protocol version 29

Capabilities: 64-bit files, socketpairs, hard links, ACLs, xattrs, symlinks,
batchfiles,
              inplace, IPv6, 64-bit system inums, 64-bit internal inums

But Only dirs retained their ACLs and I got these errors on the files:

Was wondering if you knew the source of the problems in this situation?
Thanks so much for your help.
