/* [dm] this being undefined without us adding it here means there is
no tss cleanup on windows for boost lib?
we don't care for now esp on windows only
the boost source says:
This function's sole purpose is to cause a link error in cases where
automatic tss cleanup is not implemented by Boost.Threads as a
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.
