Right.  Yes, Unison can synchronize permission bits in Cygwin-- see the -perms
preference.  However, this will only work if the underlying file system supports
it.  In particular, it won't work in Win9x, which doesn't support file
permissions, or on a FAT file system (in either Windows or Linux), which also
has no permissions.  It should work fine on NTFS, subject to the limits of
Cygwin's Unix permissions model-- see e.g.
