Only use -Wno-unused-parameter with g++.
Use libtool to create libcc. Have users of libcc use the libcc.la (libtool archive). I noticed this because libcfgclient's tests only linked with cc/data.o but build using Sunstudio showed it used libcc's session also. So instead of just linking with cc/session.o (which does work), I chose to link with libcc -- and noticed it was not using libtool. (Later will change other linking with foo.o object files to use libtool .la files instead. Also for Sunstudio support a minor patch for src/lib/cc/session_unittests.cc may later be committed.) No trac ticket for this. It was discussed with jinmei via jabber. git-svn-id: svn://bind10.isc.org/svn/bind10/trunk@2316 e5f2f494-b856-4b98-b285-d166d9295462
