If we require C99 library features like this, then I
think we should add a configure test for them. Strange
breakage at runtime is rather worse than a failed build.
(That's not the same as testing for a C99 compiler, since
one can have a C99 compiler like gcc with a C90 library.)
The fewer configure tests we need, the better. Happy to replace %zu with %llu
and forget about it. It's not worth a fuss.
