         - remove dependency on sys/queue.h on freebsd (patch by Vanilla Hsu).
         - configure now prepends -O3, not appends it, so one can still
           override it.
+        - disable poll backend on AIX, the poll header spams the namespace
+          and it's not worth working around dead platforms (reported
+          and analyzed by Aivars Kalvans).
