stdbool is C99 standard feature.

We are still targeting C89, not C99.

Another reason not to depend on stdbool is that, so far as I can see,
the standard does not promise that type _Bool has size = 1 byte.
We have to have that because of on-disk compatibility requirements.

I think the latter is easily fixable, or forceable to be one byte.
Why C89, and not C99 ? Virtually all compilers for last 4 years have/ had C99 support.
