Regards, Helge!

This is the fragment of $(BOOST_ROOT)/boost/memory_order.hpp:

namespace boost
{

enum memory_order
{
    memory_order_relaxed = 0,
    memory_order_acquire = 1,
    memory_order_release = 2,
    memory_order_acq_rel = 3, // acquire | release
    memory_order_seq_cst = 7  // acq_rel | 4
};

} // namespace boost

My questions: 

1) Where is the memory_order_consume constant? I failed to compile your
"Double Check Singleton Pattern" sample, because it uses
"memory_order_consume" constant.
2) How soon Boost.Atomic will be included into Boost release?

Best,
Andrew.
