What I meant was, you should not have an asterisk on the right side  
of a CNAME record, after the token "CNAME". So this is something you  
should *not* do:

any.thing.    CNAME    *.anything.

The example you gave works fine. It would also work fine like this:

*.foo.com. IN CNAME a.abc.com.
*.abc.com. IN A
