C99 requires both types.  C89 requires neither, and Tandem provides just
one of them as an extension to C89.  That's allowed.

No, we could argue that only if we assumed C99, which we don't.
Maybe in 10 or 15 years we can assume C99, but by then the issue
will be moot, as newer Tandem releases support both.
