The third one is built against the static runtime library, the second 
against the dynamic runtime library (in other words these differ depending 
which code generation options you select in your IDE).

Define BOOST_ALL_DYN_LIB in your project settings->defines.

_DLL indicates that the dll runtime is in use, but for deployment reasons 
many people prefer to still link Boost statically: hense this is the 
default.
