The boost_*.lib files are the import libraries to use the boost DLLS.
The libboost_*.lib files are the libraries for static linking.

The default is that the boost libraries are statically linked. If you 
#define BOOST_ALL_DYN_LINK then the DLL versions will be linked.

If you #define BOOST_ALL_NO_LIB then the automatic linking is disabled, 
and you have to specify the boost libraries in the linker command line.

All these defines can be configured in <boost/config/user.hpp>
