OK, if NTFS ACLs are that different from POSIX ACLs then it probably
won't make sense to use that to backup a FS. As star supports the
RMT protocol nicely even on Cygwin backups using star may make sense.
You could do a lot on Win9x if there was a function to get/set DOS file flags
by using POSIX filenames. As I did not install cygwin sources for compilation,
it would probably not make sense if I send a (untested) patch for that.

I'll have a lookt at it. A Solaris ACL implementation for star will be
available soon (when the Linux guys start to enhance star for Linux.

Let's just wait for this and see what happend with the Linux code.
The persons involved with ACLs on Linux like to make it POSIX compliant.
Maybe some of the code can be reused.
