If it is not a throw expression it ought to be something with similar
semantics, such as a function with __attribute__((__noreturn__)) (or
whatever it is spelled for a particular compiler), so the compiler knows
that no code past this point is ever executed.
Else you may get spurious warnings about missing return statements.
In fact, I'd suggest that boost::throw_exception() be tagged by such
an attribute (on platform that support it).
