I think I suggested the need for that in the beginning. It is an important case as you've found.

I agree that the name is long, but it is clear.
What about BOOST_NOTHROW? It doesn't transition well to an all-C++11 world (only noexcept), but both throw() and noexcept mean the function emits (or should emit) no exceptions, so the name conveys the right idea. Maybe BOOST_THROWS_NOTHING to avoid the old connotation of "NOTHROW"?
