According to the Unison manual (http://www.cis.upenn.edu/
~bcpierce/unison/download/beta-test/latest/unison-
manual.html#unisondir), on Unix hosts Unison looks in order in $UNISON
and $HOME/.unison; on Windows hosts it looks in order in $UNISON,
$USERPROFILE\.unison, $HOME\.unison, and C:\.unison. So there are two
issues here:
(1) Unison is looking in $UNISON last. This is clearly wrong, and if
fixed would allow you to solve your problem by setting
UNISON=/home/volker/.unison. But here's something I don't understand:
on my Cygwin host both UNISON and USERPROFILE are set, but UNISON takes
precedence. ?? Are you sure this section of code is the operative one
here? What happens if you export UNISON=/home/vzell/.unison?
(2) It seems that Unison treats Cygwin as a Windows OS for this purpose,
so that it looks in $USERPROFILE/.unison before $HOME/.unison. This is
arguably wrong, but I think I'll have to pose the question on unison-
hackers.

And this patch solves the owner and group sync problem? Sorry but it's
not obvious to me.
You say Unison "didn't honor" the owner and group preferences. What
exactly happened? Did it just not sync the owners and groups, or did it
give you error messages?

Yup. This is documented in /usr/share/doc/Cygwin/unison-2.10.2-
1.README. Gerrit Haase has been after me to provide a generic build
script for building Unison from the source package, and when I make one
it will include this.
Thanks for your report. As soon as I'm sure that I have the right
corrections, I'll release a new version that includes the fixes.
Andrew.
