        It looks as though _GLIBCXX_HAVE_GTHR_DEFAULT is defined by the std lib when it's in thread safe mode, so I'm leaning towards adding: #ifdef __GLIBCXX__ // gcc 3.4 and greater: #ifdef _GLIBCXX_HAVE_GTHR_DEFAULT #define BOOST_HAS_THREADS #else #define BOOST_DISABLE_THREADS #endif #endif To our libstdcpp3.hpp config file, which I think will take care of it, albeit not in a way that everyone will appreciate (it will force threading on whenever the std lib is also thread safe). Thoughts? John.
