Well, we were ignoring the errors in the build system and then you chose
to change that. So if you want to enforce the werror flag, you should
fix the fallout. The other option is to stop enforcing werror in this
case as we did until now.
The problem is that despite 'old/broken' libraries, you made it
unbuildable.
