Yes.

On my box, res_init and res_search both resolve via #define to
res_9_*.  I'm not sure about dn_expand.  So whatever happens by
autoconf default in these cases, we're not searching for the right
functions unless we include the necessary headers to #define them to
BIND 9 versions.

All of them, I'm afraid.  I'll take a look, but I think this requires
custom macros for Panther, at least.

BTW, the by-hand workarounds documented in Christus's pages are the
same as what I was doing.
