New Revision: 85531
URL: http://svn.boost.org/trac/boost/changeset/85531

Log:
Switched to boost::detail::lightweight_mutex instead of boost::mutex from Boost.Thread to avoid false dependencies on Boost.DateTime, Boost.Chrono and Boost.System. This should hopefully resolve linking problems on MinGW.
