IPv6 support for Apache
ftp://ftp.inria.fr/network/ipv6/freebsd/New.tar.gz includes a modified
Apache 1.2.1.

(I think)
The changes included are below. Don't seem backwards compatible, but
that isn't a big deal. Not sure if the APIs are standardized enough
to make it worth considering for 1.3 (erm... or if anyone has 6bone
connectivity anyway), but for 2.0. Not overly complex, although
I would bet things are missing in a few places.
