In Boost release 1.31, the Boost.Threads library doesn't support static 
linking. This limitation will be removed in the next release (coming 
soon) for:

a) anyone using the pthreads implementation of Boost.Threads
b) anyone using Visual C++ on Win32

Hopefully it will be removed for other Win32 compilers in the future.
