[Boost-users] [thread] Can Boost.Thread use Boost.Atomic without falling on a compatibility issue?

Hi, in order to fix this issue, https://svn.boost.org/trac/boost/ticket/5752 : "boost::call_once() is unreliable on some platforms", I would like to use Boost.Atomic as suggested on the ticket. As Boost.Atomic is not a header-only library the user would need to link with boost_atomic. Is this an acceptable change? I'm requesting this as recently there were some people reactive to some changes in Boost.Thread. Would this be considered an compatibility issue? If yes should the fix for the call_once issue be included if the user request it using conditional compilation or even go on a separated version of Boost.Thread? Thanks, Vicente
