Evaluating addrFlags from use of Network.Socket.getAddrInfo causes exception

Using GHC 6.10.2 under Mac OS X 10.5.6 it does not appear that you can access the 'addrFlags' returned by getAddrInfo, you get the exception: *** Exception: unpackBits: unhandled bits set: 8

I just sent a fix to Johan. I can't attach it here, because the Trac install is broken and won't accept attachments.

  * Make getAddrInfo tolerant of unknown bits (ticket #8).
  On OS X, getaddrinfo can return with bits set that have no corresponding
  definitions in the <netdb.h> header file.
