What Roger is referring to is the situation where boost::filesystem's
DSO no longer depends boost_system, but the header files still use
boost::system in inlined methods. That, however, is very unlikely (and
probably would be treated as a Boost bug), as it would cause a lot of
FTBFS issues, even with --add-needed.
