XEmacs will raise an exception on any platform when the call to chmod
fails. This can happen, for instance, if you do not own the file being
chmod'ed. I believe that this can also happen for certain file modes on
SMB file systems. Someone with a Linux system and a Samba mounted file
system could verify this.

This is not a platform bug. IMO, Gnus should not request a file mode
that the underlying filesystem cannot support.
