C++11 doc defines std::atomic::fetch_or() and std::atomic::fetch_and() only for Integral types. In this way, MSVC++ 2012 std::atomic< bool > is not implements this functions. Does anyone know why?

I found only this solution. Implement specialization for std::atomic_fetch_or and std::atomic_fetch_or.

namespace std
{
    template<>
    inline bool atomic_fetch_or<bool>(std::atomic<bool>* atom, bool val)
    {
        bool bRes = !val;
        atom->compare_exchange_strong(bRes, true);
        return bRes;
    }

    template<>
    inline bool atomic_fetch_or_explicit<bool>(std::atomic<bool>* atom, bool val, std::memory_order order)
    {
        bool bRes = !val;
        atom->compare_exchange_strong(bRes, true, order);
        return bRes;
    }


    template<>
    inline bool atomic_fetch_and<bool>(std::atomic<bool>* atom, bool val)
    {
        bool bRes = true;
        atom->compare_exchange_strong(bRes, val);
        return bRes;
    }

    template<>
    inline bool atomic_fetch_and_explicit<bool>(std::atomic<bool>* atom, bool val, std::memory_order order)
    {
        bool bRes = true;
        atom->compare_exchange_strong(bRes, val, order);
        return bRes;
    }
}

Unfortunately it is inconvenient to use as if it were a built-in operators.
