Line 52 of <sys/socket.h> in 4.6.2-RELEASE contains:

      49 /*
      50  * Data types.
      51  */
      52 typedef u_char          sa_family_t;
      53 #ifdef  _BSD_SOCKLEN_T_
      54 typedef _BSD_SOCKLEN_T_ socklen_t;
      55 #undef  _BSD_SOCKLEN_T_
      56 #endif

Make sure you include <sys/types.h> before <sys/socket.h>.

Wrong header order.  The <sys/socket.h> header uses some of the types
that are defined in <sys/types.h>.

PS: When you reply to a post, it's a good idea to Cc: both the list
and the original sender.  I would have missed your followup post, if
I hadn't been looking at the subjects of the list carefully enough.
