My shared drive from Linux is reiserfs, specifically reiser-3.6.19-3
I have no idea how to make a NTFS filesystem on linux. And even if I could,
until the latest linux-ntfs programs, I couldn't write to it.

Using the magic of samba, the linux native fileserver mounts are made 
to look like
something accessible on windows.

I set cygwin to smbntsec.
I logged out of windows, and logged back in. I verified that cygwin was set
correctly. I created a new emacs-22.1 tree on my samba fileserver.
I ran diff on windows again. Exact same problem.
