Not everybody is running a compiler released within the last 4 years.
The short answer is that C99 doesn't appear to offer enough advantage
over C89, *for our purposes*, to justify freezing out older systems.
stdbool is a perfect example of an addition that offers precisely
zero actual functional improvement. All it would be for us is an
additional autoconf headache and portability hazard.
