I am no avahi expert so I could be wrong. I think avahi/zeroconf only
uses the dns protocol, but won't use the glibc name resolution functions
with link local addresses. So this use case won't affect the Vista/OS X
like name resolution.
The relevant changes in glibc 2.5 are address sorting related. I don't think
it allows disabling AAAA queries in gai.conf
From glibc NEWS:
* For Linux, the sorting of addresses returned by getaddrinfo now also
handles rules 3, 4, and 7 from RFC 3484. I.e., all rules are handled.
Implemented by Ulrich Drepper.
* Allow system admin to configure getaddrinfo with the /etc/gai.conf file.
