I'd think so. I'm using 6to4, if that matters. Here's the snippet from config.log:t

configure:25519: checking whether to enable IPv6
configure:25534: result: yes
configure:25548: checking if PF_INET6 is available
configure:25583: g++ -o conftest -g -O2 -g conftest.cpp >&5
configure:25587: $? = 0
configure:25593: ./conftest
configure:25597: $? = 0
configure:25599: result: yes
configure:25624: result:
configure:25643: checking for IPv6 split-stack requirement
configure:25666: result: no
configure:25672: checking for sin6_len field in struct sockaddr_in6
configure:25703: g++ -c -g -O2 conftest.cpp >&5
configure:25710: $? = 0
configure:25727: result: yes
...
#define USE_IPV6 1
#define IPV6_SPECIAL_V4MAPPED 1
#define IPV6_SPECIAL_SPLITSTACK 0

Here's cache.log with debug_options 0,5 78,9:

Turns out my previous conjecture was wrong. Those warnings appear even after I've commented out all the IPv6 bits in the ACLs. Here' the complete lines from cache.log, in case it matters:

2009/05/20 23:46:02| WARNING: Netmasks are deprecated. Please use CIDR masks instead.
2009/05/20 23:46:02| WARNING: IPv4 netmasks are particularly nasty when used to compare IPv6 to IPv4 ranges.
