Thanks for this. However, what you do not say is that you also seem to
need to compile in your contributed ACL proxy authentication patches
( otherwise squid logs
"Invalid ACL type 'proxy_auth'" in cache.log.

Your patches do not seem to be available for squid versions more recent
than 1.1.14. Do you intend to release for the current version (1.1.18) or
will those for 1.1.14 work cleanly with 1.1.18?

Also, is it know if this functionality will be incoporated into the main
development stream of future squid versions?
