Could be.  I don't know much about rsync.  However, if that is the uid/gid,
it maps to -1 (don't know why it's represented as a 32-bit value though.)
Anyway, if you and I are right, then my WAG is that your '/etc/passwd'
and/or '/etc/group' file(s) are wrong.
See <http://cygwin.com/cygwin-ug-net/ntsec.html#ntsec-ids> for more details 
on Cygwin special IDs.
