I can't speak for the libraries you mention above. But regarding Boost
libraries in general many Boost libraries are unaffected in their public
interface whether you compile with C++03, C++11, C++14, or C++17
support. If a library is affected in its public interface depending on
the level of C++ support it should document this and, needless to say if
it is a built library whether static or shared, it should have a
distinct library name depending on its differing public interfaces.
