They do, it just wasn't explicitly stated, and wasn't tested (which allowed 
one to throw enums by mistake).

If 'e' doesn't derive from std::exception, the code won't compile when 
BOOST_NO_EXCEPTIONS is defined, and the original purpose of 
boost::throw_exceptions was precisely to support the case when 
BOOST_NO_EXCEPTIONS is defined.
