The MSVCRT we're using in GCC is much, much older, and that won't change
anytime soon, I don't think.

You _might_ get the code to compile a `%zu` format by playing some macro
tricks, but executing the result would still not work.

It sure would be nice if we could use all that POSIX promises... but we
can't. Sorry...
