And if you do not have a /etc/gai.conf (for instance on recent Fedora), you should have an example somewhere within /usr/share/doc (on Fedora 14, it is at /usr/share/doc/glibc-common-2.12.90/gai.conf) which you can copy over to /etc/gai.conf.

Thanks for the correction; I did not realize that this file was optional.

For reference, I started with the default gai.conf provided by the Debian libc-bin package, version 2.11.2-8, and uncommented all the "label" lines *except* the one with the 6to4 prefix. The result should look something like this:

label ::1/128 0
label ::/0 1
#label 2002::/16 2
label ::/96 3
label ::ffff:0:0/96 4
label fec0::/10 5
label fc00::/7 6
label 2001:0::/32 7

This excerpt should work as a complete configuration should you happen to lack a default gai.conf file.

Thank you! I'd been trying to figure out why my gai.conf wasn't forcing ipv6 for ages.
