[Olena] New warning in G++, and in user code.

Hello, I recently updated my system, and g++ (Debian 4.8.1-10) 4.8.1 came in with. With this new version, I got the following bug resolved: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33255 But it causes a lot of warning for my code using milena. I propose the following patch that suppress the warnings from user code. -- Armand Leclercq EPITA 2013 Assistant C/Unix
