Since 5a468b38b6 we use SOL_LOCAL for the 2nd argument of getsockopt() however Lion added the define SOL_LOCAL set to 0, which is the value to the 2nd argument of getsockopt() for Unix sockets on Mac OS X. So instead of using the define just pass 0 so we restore compatibility with Snow Leopard and Leopard.
