Glibc 2.0 has no support for IPv6, pretty much.  It probably doesn't even 
define struct sockaddr_in6, so assuming you have some autoconf-like mechanism 
to decide whether IPv6 is supported there probably isn't anything difficult 
here.

Glibc 2.1 does have some IPv6 support.  The reason it is not complete is that 
the API has been changing rapidly over the past year or so.  Functions like 
getipnodebyname are relatively recent additions and nobody had time to write 
the support between the time the API was changed and the time glibc 2.1 was 
frozen.  It is now in the development sources of what will become glibc 2.2.

Name lookup aside, I think the IPv6 support in the current release of glibc 
2.1 ought to be functional enough for most people.  The getaddrinfo function 
does provide working IPv6 name lookup, though possibly not in the form you 
want.
