Richard/Segher: Are we in agreement that we can move forward with updating to c++11 as the minimum version? I have made the simple change locally to modify the flag and verified that I got the exact same test results with/without the change. I can look into the work to add a configuration warning if the compiler doesn't support c++11, but wanted to make sure we are on the same page before doing so.
