I pushed a commit to resolve windows build error.

• win/cubridcs/cubridcs.def
• win/cubridsa/cubridsa.def

If you change host_lookup.c as I suggested, the windows build is successful.

Oh I see. I will try to apply it and then commit again.

I will execute "git rebase to" eliminate conflict error.

In master process and broker, we need to change the code execution flow to allocate system parameters.
