[Boost-users] [thread] mixing boost::mutex from different boost versions

Hi, are boost::mutexes from different boost versions ABI compatible, provided that the modules (boost thread library, my own) are compiled with the same compiler? My question arises because I'm creating a windows DLL with class methods taking a boost::mutex& from let's say boost 1.38, but an application (the EXE) might use e.g. boost 1.39. Klaus Triendl
