Hi Romain:

Pushed to trunk, thanks for catching that, that's definitely should
use log2 no matter C++03 or C++11,
but I think GCC allows the usage of C++11 according to
https://gcc.gnu.org/install/prerequisites.html :P
Yes, we should be able to use C++11.  I'd like to get that to C++17 at 
some point, but I think the biggest problem is the desire to support 
bootstrapping on something like centos7/rhel7.
