Ignore my question. I don't think it's relevant, nor do I think there's
any need for Cygwin-specific code in emacs to deal with this. As I
understand it, this is a filesystem problem: Samba returns a fake SID to
Windows, so Cygwin can't determine the correct uid/gid. Jari, you were
already told on the Cygwin list how to work around this problem. Why
not just do it?
