 Thanks for adding this.  It appears to work with FreeBSD 8.4-BETA1 #25 =
 r248493M.
 
 The only point of contention is using sizeof(char) rather than =
 sizeof(int).   Using char
 is extending the exception from recvmsg and IP_TOS.  =
 sendmsg/recvmsg/setsockopt
 should all be using the same size.  I had to read the kernel code to =
 work out that it
 was a 'char' as the header files say 'int' and that is what setsockopt =
 uses.
