In Unix the arg optval points to a struct timeval, in windows to a
(32bit) int, no mystery here. The latter is the timeout in
milliseconds. Further a non-zero timeout less then 500 (msec) is taken
as 500 msec.

Of course, its the same issue.

You will need to convert from milliseconds here.

Unfortunately this does not work (a recv timing out). The socket in
wine is non-blocking internally, any blocking will be done in the
function do_block() using a select(). SO_RCVTMO has no effect there.
