 Please someone quickly review the attached patch.

 I believe it solves the build error for NetBSD:
 http://bind10.isc.org/~tester/builder/BIND10/20100922005000-NetBSD5-amd64/logs/build.out

 The offending parameters of PyArg_ParseTuple() is the variable argument
 part, so we should be able to omit the cast in the first place (in fact, I
 omitted cast for the python binding of the EDNS class in trac #311).  In
 that sense this change should be harmless.

 IMO the NetBSD's behavior on this point is deviant (again), but since we
 can save them for a trivial, harmless change, we should do it.

 I don't think we need a changelog entry for this.
