Have a look at the thread on the users list:
Re: [Boost-users] Re: Memory leak reported using threads library

Basically because:
#if (defined(_DLL) || defined(_RTLDLL)) && defined(BOOST_DYN_LINK)
#elif defined(BOOST_DYN_LINK)
# error "Mixing a dll boost library with a static runtime is a really
bad idea..."
# define BOOST_LIB_PREFIX "lib"

as the explanation of "bad idea".
But perhaps this reasoning should be mad more explicit. At least as an
extended comment in the autolink file as I already suggested.
