if you don't need TSVN to run on win2k but only on XP and later, then
you can remove the following from ext\build\apr.build:

                                <!-- With the Vista SDK, it's necessary to define _WIN32_WINNT to
0x0501 to gt IPv6 support,
                                     but that value also breaks the app on Win2k. To get a stub
compiled in, we must include
                                     Wspiapi.h, this will make it work again on win2k. -->
                                <replacestring from='#if APR_HAVE_IPV6' to='#if APR_HAVE_IPV6
#include "Wspiapi.h"' if="${ipv6 == 'enabled'}" />

I'll remove this for the trunk build now, since we don't support win2k
for that version anyway anymore.
