Really? It's not documented though, and that led me to thinking
it could possibly go away/be replaced in the future.

I'm not too fond of the syntax
typedef int blah __attribute__((mode(xxx)));
mainly because the "int" gets ignored. It just seems quirky. But if no
one else sees a problem with it, I'll stick to the original documentation
I wrote.
