I haven’t used wccp2_return_method or wccp2_forwarding_method in my configurations but both default to ‘gre’ anyway.

I build squid using the FreeBSD port infrastructure. configure seems to have been run with these options:

'--with-default-user=squid' '--bindir=/usr/local/sbin' '--sbindir=/usr/local/sbin' '--datadir=/usr/local/etc/squid' '--libexecdir=/usr/local/libexec/squid' '--localstatedir=/var' '--sysconfdir=/usr/local/etc/squid' '--with-logdir=/var/log/squid' '--with-pidfile=/var/run/squid/squid.pid' '--with-swapdir=/var/squid/cache/squid' '--enable-auth' '--enable-build-info' '--enable-loadable-modules' '--enable-removal-policies=lru heap' '--disable-epoll' '--disable-linux-netfilter' '--disable-linux-tproxy' '--disable-translation' '--enable-auth-basic=DB MSNT MSNT-multi-domain NCSA PAM POP3 RADIUS fake getpwnam NIS' '--enable-auth-digest=file' '--enable-external-acl-helpers=file_userip time_quota unix_group' '--enable-auth-negotiate=kerberos wrapper' '--enable-auth-ntlm=fake smb_lm' '--enable-storeio=diskd rock ufs aufs' '--enable-disk-io=AIO Blocking DiskDaemon IpcIo Mmapped DiskThreads' '--enable-log-daemon-helpers=file' '--enable-url-rewrite-helpers=fake' '--disable-ipv6' '--disable-snmp' '--enable-ssl' '--with-openssl=/usr' '--enable-ssl-crtd' '--enable-htcp' '--disable-forw-via-db' '--disable-cache-digests' '--enable-wccp' '--enable-wccpv2' '--disable-ident-lookups' '--disable-eui' '--enable-ipfw-transparent' '--disable-pf-transparent' '--disable-ipf-transparent' '--disable-follow-x-forwarded-for' '--disable-ecap' '--enable-icap-client' '--disable-esi' '--enable-kqueue' '--enable-stacktraces' '--prefix=/usr/local' '--mandir=/usr/local/man' '--infodir=/usr/local/info/' '--build=i386-portbld-freebsd9.2' 'build_alias=i386-portbld-freebsd9.2' 'CC=cc' 'CFLAGS=-O2 -pipe -I/usr/include -g -fno-strict-aliasing' 'LDFLAGS= -pthread -Wl,-rpath=/usr/lib:/usr/local/lib -L/usr/lib' 'CPPFLAGS=' 'CXX=c++' 'CXXFLAGS=-O2 -pipe -I/usr/include -g -fno-strict-aliasing' 'CPP=cpp' --enable-ltdl-convenience

There are a few patches to the source in the FreeBSD port (/usr/ports/www/squid33/files), but doubt they would affect this:
