As has been said before, bind will not accept a CNAME for the
domain record.  Maybe other DNS implementations do, but not
the latest stable version of bind.

This is due to the fact that the domain name has other information
associated with it and CNAME records cannot/should not have any
other information other than what record they're CNAME'ed to.
