Ugh, top-posting.  Reformatted.

Aha - just as I suspected - ACLs at work (the file x is accessible to the
administrators group, while the file y is not).  Further information would
be useful, such as the attached output of 'cygcheck -svr'; see
cygwin.com/problems.html.  And that mkgroup_ as the group name is fishy;
your /etc/group file is probably out-of-date, so see the output of
'mkgroup --help' to remedy that.

It is part of coreutils-5.3.0-6.  Have you upgraded your installation in a
while?
