Shucks, not sure :-(

My suspicion is that STLport had std::unordered_* for a while (inherited 
from the old SGI STL), then moved them into std::tr1:: and now back to std:: 
again.

Of course the early versions probably aren't completely compatible with what 
ended up in the std either :-(

I guess just remove the code that sets BOOST_NO_STD_UNORDERED here, and 
stick with the original plan, if that breaks obsolete STLport versions then 
too bad I guess....?

Not quite as the former relates to what's in std:: and the latter std::tr1::

HTH, John.
