I have updated the patch in the ticket #5752 with the C++11 definition of 
atomic_flag. Note that the new patch disables the 
BOOST_THREAD_PROVIDES_ONCE_CXX11 macro when constexpr is not available.

The patch also adds some heuristic code for detecting an atomic-compatible 
integer type to even better avoid using the spinlock pool of Boost.Atomic.

The modified files are attached as well. These are 
boost/thread/pthread/once.hpp, boost/thread/detail/config.hpp and 
libs/thread/src/pthread/once.cpp.
