--- Comment #22 from Stewart Gordon <smjg at iname.com> ---
I was beginning to think this makes it part of the function type rather than
being a declaration attribute.  I make out from what you say that, for reasons
of parsing convenience, syntactically it's a declaration attribute but the
semantic of it thereas is to pass it through so that it becomes part of the
function type.  Have I got this right?
