Comment (by anonymous):

 The problem is actually deeper than expected:

 1. create new MSVC 10 or 11 console project and add boost include and
 linker paths

 2.
 {{{
 #include <boost/thread/tss.hpp>
 }}}

 3. add global variable
 {{{
 boost::thread_specific_ptr<std::wstring> msg;
 }}}

 4. compile and link

 5. linker error

 => there is obviously a bug in the boost dependency management. Both when
 building the boost package and even later when linking a project the
 depedency of boost::thread from boost::chrono is not detected.
