+Subject: Detect presence of dns_zone_setmaxrrperset
+
+
+Because it were backported into bind-9.16 branch by upstream and testing
+of simpler variant fails in some cases. This assumes these call do not
+appear only after 9.18.28, but may be backported into previous versions.
+Tests just call presence and assumes dns_db_setmaxtypepername will be
+present also.
