  - boost libraries will try to be smart and use the (pretty but often not useful) auto-linking feature of MSVC
    So before calling `conf.check_boost` you might want to disabling by adding:
    	conf.env.DEFINES_BOOST += ['BOOST_ALL_NO_LIB']

 Passing `--boost-linkage_autodetect` might help ensuring having a correct linkage in some basic cases.
