Based on git bisect, this appears to be the patch that causes it:

uthor: Yang Tse <yangsita_at_gmail.com> 2010-12-16 08:18:57
Committer: Yang Tse <yangsita_at_gmail.com> 2010-12-16 08:18:57
Parent: e03a65c3d9b2eb47f6ce6234823913638cb6c816 (ares_inet_net_pton: fix non-rejection of some malformed literals)
Branches: master, remotes/origin/master
Follows: cares-1_7_4
Precedes:

     fix compiler warning: conversion may lose significant bits

My test is:

make distclean; ./configure; make

I tested on Fedora 11 64bit and Fedora 13 32-bit.

I'm curious if anyone can get this to compile on any form of Linux?

Thanks,
Ben
