This may be doing what it does for the wrong reasons.
Just to point out that those warnings in APR_CHECK_GETNAMEINFO_IPV4_MAPPED derive from exactly the same snippet in APR_CHECK_GETNAMEINFO. So, any warnings here are red herrings (or that check has exactly the same warnings).
Regardless, the macro was passing NI_NUMERICHOST instead of NI_NAMEREQD which is what is needed to trigger the IPv4-IPv6 mapping oddity. I'll have to leave it to someone else to backport to APR 0.9.x so it can be used in httpd 2.0.x. -- justin
