Now I consider it you might be right. Here's a list of those places:

[andrew(at)alphonso src]$ grep -rl HAVE_IP .
./include/pg_config.h.in
./include/libpq/ip.h
./include/pg_config.h
./bin/initdb/initdb.c
./Makefile.global.in
./backend/libpq/pqcomm.c
./backend/libpq/ip.c
./backend/libpq/hba.c
./backend/utils/adt/pgstatfuncs.c
./backend/utils/adt/network.c
./Makefile.global
./interfaces/libpq/ip.c
./port/getaddrinfo.c

Can we even get this done for 8.1, or is it too late? If it's too late
we need to document heavily that we do not (fully) support IPv6 on
Windows yet.

Can someone please try running a build from CVS tip made on a modern box
(W2k3 or XP >= SP1 I believe) on a non-modern box (e.g. W2k) and see if
anything blows up? If it does then we either have to finish this work
now or revert the config file changes, I think.

cheers
