I don't see how this can happen unless:
a) your boost/thread/detail/config.hpp is out of date, or
b) you're defining BOOST_THREAD_USE_DLL or BOOST_DYN_LINK.

If you're sure neither of these is the case, could you determine which 
branch is being chosen in the complicated #if near the top of 
boost/thread/detail.config.hpp that looks like the following?

#if defined(BOOST_HAS_WINTHREADS)
#   if defined(BOOST_THREAD_BUILD_DLL) //Build dll
#       define BOOST_THREAD_DECL __declspec(dllexport)
#   elif defined(BOOST_THREAD_BUILD_LIB) //Build lib
#       define BOOST_THREAD_DECL
#   elif defined(BOOST_THREAD_USE_DLL) //Use dll
#       define BOOST_THREAD_DECL __declspec(dllimport)
#       define BOOST_DYN_LINK
#   elif defined(BOOST_THREAD_USE_LIB) //Use lib
#       define BOOST_THREAD_DECL
#   else //Use default
#       if defined(BOOST_MSVC)
             //For VC++, choose according to threading library setting
#           if defined(_DLL)
                 //Threading library is dll: use Boost.Threads dll
#               define BOOST_THREAD_USE_DLL
#               define BOOST_THREAD_DECL __declspec(dllimport)
#               define BOOST_DYN_LINK
#           else
                 //Threading library is lib: used Boost.Threads lib
#               define BOOST_THREAD_USE_LIB
#               define BOOST_THREAD_DECL
#           endif
#       else
             //For compilers not yet supporting auto-tss cleanup
             //with Boost.Threads lib, use Boost.Threads dll
#           define BOOST_THREAD_USE_DLL
#           define BOOST_THREAD_DECL __declspec(dllimport)
#           define BOOST_DYN_LINK
#       endif
#   endif
#else
#   define BOOST_THREAD_DECL
#   if defined(BOOST_THREAD_USE_LIB) //Use dll
#       define BOOST_THREAD_USE_DLL
#       define BOOST_DYN_LINK
#   elif defined(BOOST_THREAD_USE_DLL) //Use lib
#       define BOOST_THREAD_USE_LIB
#   else //Use default
#       define BOOST_THREAD_USE_LIB
#   endif
#endif // BOOST_HAS_WINTHREADS

Thanks,
