        I've built and installed boost on a WinXp system with VS.Net
2003.  I'm trying to use it in a static CRT project.  I get the
following error whenever I compile:

        I noticed that this is happening because BOOST_DYN_LINK is
#defined in config.hpp.  Apparently dynamic linking is the default for
Boost? 

Windows does not support registration of clean-up functions for
thread-specific storage (TSS, or TLS), but it does notify DLLs when a
thread exits and this gives DLLs a chance to clean-up their
thread-specific storage. So in order to make TSS work correctly,
Boost.Threads is designed to be built only as a DLL on Windows. This
means, as the error message says, that you need to use the DLL version
of the CRT.
