Maybe someone ( =you? :-) ) should submit a patch for this, since I keep
providing patches for stuff I barely care or know anything about to get
other patches (e.g. the errno one to provide relatively useful error
messages in applications) in that I'm interested in...

Also, if we do this, ffserver and tcp.c need to be made ipv6-compatible, and
I'm definitely not the right person to do that...
