Re: [boost] compiling boost using C++11 atomics

Hi,

Is there any particular reason that boost isn't being compiled with BOOST_AC_USE_STD_ATOMIC and BOOST_SP_USE_STD_ATOMIC (by default) when C++11 support in g++ is available (g++ >= 4.7)?

Support for <atomic> in earlier C++11 implementations wasn't reliable enough compared to shared_ptr's platform-specific implementations. Things nowadays have probably already reversed though, with <atomic> being more reliable. I could turn it on by default when BOOST_NO_CXX11_HDR_ATOMIC isn't defined, which according to Boost.Config would enable it on g++ 4.9 and above.
