      This function's sole purpose is to cause a link error in cases where

      reminder that user code is responsible for calling the necessary
      functions at the appropriate times (and for implementing an a
      tss_cleanup_implemented() function to eliminate the linker's
      missing symbol error).

      If Boost.Threads later implements automatic tss cleanup in cases
      where it currently doesn't (which is the plan), the duplicate
      symbol error will warn the user that their custom solution is no
      longer needed and can be removed.
