Don't call bind when opening a socket.

The call to bind, thoug working fine under GNU/Linux, seems not to work under
other operating systems. It didn't work under FreeBSD and Mac OS X with the
`bind' call but without.
I think `bind' may only be neccessary if we want to bind to a specific
interface. It might be a good idea to add the possibility later, so I only
commented the code for now.
