boost::throw_exception( x ) has always had an implicit requirement that x 
needs to derive from std::exception (because it's declared as taking 
std::exception const& as an argument when BOOST_NO_EXCEPTIONS is defined). 
This requirement wasn't enforced though. We are enforcing it now, hence the 
error.
