Unfortunately, it won't go anywhere with the Austin group without prior
implementation practice; and even then it is unlikely.  Basically, since
%zu is already specified by C99 and POSIX, the only reason that you
would need PRIuSIZE is if you are targetting a non-POSIX system that
lacks %zu in the first place.  But if a platform already lacks %zu, what
makes you think they are going to have PRIuSIZE?

If we are going to have any luck standardizing it anywhere, it would
have to be in the GNU Coding Standards, since that is the only document
that specifically talks about portability issues to non-POSIX platforms
and can afford to invent extensions to C99 and POSIX that we are willing
to assume among all GNU projects.
