BIND 9.3.0: 'check-names response' refuses to ignore

I'm running BIND 9.3.0 on Solaris 9.

The code indicates that the following behavior is the default:

check-names response ignore;

But named behaves as if the default for responses is 'warn', not 'ignore'.
E.g. it logs messages like:

in.named[1688]: resolver: notice: check-names warning union+city-nj.addresses.com/A/IN
in.named[1688]: resolver: notice: check-names warning shoprite.com/NS/IN
in.named[1688]: resolver: notice: check-names warning 12.113.186.146.in-addr.arpa/PTR/IN

Adding 'check-names response ignore;' to the global options does not appear to help.

Any ideas as to how to get check-names response to ignore?
