	I have the following problems with socket functions:

	(1) SO_USELOOPBACK (error message: SO_USELOOPBACK - not supported)

	opt = 1;
	if (setsockopt(fd, SOL_SOCKET, SO_USELOOPBACK, (char *)&opt, sizeof(opt))
< 0)
        		report_error("setsockopt(SO_USELOOPBACK) %s:%s", cptr);

	(2) SNDBUF and RCVBUF (not even defined)

	if (setsockopt(fd, SOL_SOCKET, SO_SNDBUF, (char *)&opt, sizeof(opt)) < 0)
        report_error("setsockopt(SO_SNDBUF) %s:%s", cptr);

	(3) select() doesn't allow for enough fds

	select only allows for around 60 or so FDs, while some Unix apps use 4095!

	(4) /proc/net/tcp isn't output. This is used by Identd. If anyone wants to
add this, I'll send them all the info. It shouldn't be too hard. This isn't
a problem, but it is something I think should be added.
