Hi,

As far as I can remember,  the complete problem with asio ABI compatibility
sits in the asio/detail/atomic_count.hpp and the problem is different size
of std::atomic<long> and boost::detail::atomic_count. You may probably use
BOOST_ASIO_DISABLE_STD_ATOMIC option to make non c++11 ASIO and c++11 ASIO
ABI compatible but I never tested it. We strictly use c++11.

Best Regards,
Slavek
