We've never required C++11 Standard Library. We've only required the core 
language and the integrity compiler does support it just fine.

More than likely we're just missing an -l flag or equivalent to link to the 
necessary implementation. If that's the case, it's no different than libstdc++ 
which requires adding -lpthread to your link command-line.
