Hi,

There is a problem with Boost.Thread on windows, when BOOST_THREAD_USES_CHRONO 
macro is defined. In win32/basic_timed_mutex.hpp there are references to 
Boost.Chrono not guarded with this macro, which results in compile errors. 
Could this be fixed before the 1.51 release? I can apply the change, if 
permission is granted.
