-/* This function serves as replacement for a missing fchownat function,
-   as well as a work around for the fchownat bug in glibc-2.4:
-    <http://lists.ubuntu.com/archives/ubuntu-users/2006-September/093218.html>
-   when the buggy fchownat-with-AT_SYMLINK_NOFOLLOW operates on a symlink, it
-   mistakenly affects the symlink referent, rather than the symlink itself.
