The original one, which unfortunately did not enforce the requirement. The
current one does.

It means that if some Boost library ever passed to boost::throw_exception
an object of type that doesn't derive from std::exception, it'll lead to
compile errors under BOOST_NO_EXCEPTIONS. I'll let you figure out why.

Currently, you'll get a compile error in any configuration.
