reading this update, there are some changes I'd like to suggest.
Some (or all ;-) may be disagreeable; they all stem from me
trying to understand this update.
One question: where it refers to __has_attribute returning a
date in some cases, would it make sense to provide an example
or show the format?
By the way, gcc/doc/ does not seem to contain any documentation
of this macro? Shouldn't that be described there?
