Thanks!  I've re-compiled without the unnecessary flag, and restarted the service with a new whitelist, unfortunately i'm getting such a varying of /var/log/squid/access.log messages that I'm not sure what to google anymore.

I want to deny all access to external sites except http/https github.com but some sites seem to connect, while others don't:

~$ # this is correct
~$ curl http://github.com/
10.0.1.180 TCP_MISS/301 200 GET http://github.com/

~$ # this is correct
~$ curl https://github.com/ 
10.0.1.180 TCP_TUNNEL/200 107323 CONNECT 140.82.114.4:443

~$ # this should deny
~$ curl https://youtube.com/
10.0.1.180 TCP_TUNNEL/200 4844 CONNECT 172.217.15.110:443

~$ # this should deny
~$ curl https://google.com/
10.0.1.180 TCP_TUNNEL_ABORTED/200 5103 CONNECT 172.217.2.110:443

~$ # this is denying - but not from squid, but openssl?
~$ curl https://news.ycombinator.com/
curl: (35) OpenSSL SSL_connect: SSL_ERROR_SYSCALL in connection to news.ycombinator.com:443
10.0.1.180 NONE_ABORTED/200 0 CONNECT 209.216.230.240:443

    "--enable-ssl" is not a Squid build option.

    This is not dstdomain syntax. Remove the "*" character.
