You can't but I don't think this is what you mean.  You want them to
tail to one port number.  Well,  you are allowed to do multiple accepts
on the same original socket.  Accept returns you new sockets rather than
just twiddling the one you give it (see accept(2)), just use the REUSEADDR
option.

The only problem that remains is how to multiplex new connections into
existing ones and you can handle this with select.  Select returns
a "ready for reading" condition when there is a connection available.
