Those are typically the errors you get when linking against Boost libraries 
that were *not* also built against STLport.

That's very strange: that section of code is protected with:

#if BOOST_WORKAROUND(BOOST_MSVC,>=1400) && defined(_CPPLIB_VER) && 
!(defined(__SGI_STL_PORT) || defined(_STLPORT_VERSION))

So should never be taken when STLport is in use.

I'm not able to reproduce this either using STLport 5.1 and VC8.  What 
specific compiler options are you using and which file generated this error?

Thanks, John.
