No. Apache was not built with -DWITH_IPV6_V6ONLY. It is apache built
with dual stack support though I don't think the code is any different
if built with WITH_IPV6_V6ONLY. Nothing here is conditionally
compiled. I also checked the .h where APR_INET is defined (in
srclib/apr/include/apr_network_io.h). It is unconditionally defined
The code compiles but the server fails to run, giving an assert when
starting up. Its a simple patch. APR_INET6 could be used instead of
APR_UNSPEC in the patch.
