I wrote an http server on my own. It works a long time already with IPv4.

For the IPV6 version I changed psockaddr to sockaddr_in6.
And the proper addrlen -> sizeof( sockaddr_in6 );
I discovered that shortly after my first question about this topic here in the 
mailinglist.
Additionally the socket protocol family was changed from PF_INET to PF_INET6 
when creating the socket.

Also I have to change fpaccept the same way as fpbind.

The server then worked properly with a localhost IPV6 request from a browser
