Thanks, I'm applying the patch below. It tacifies IRIX cc.

I don't know what you will propose, but
- "enum" is fundamentally the right concept for this; "enum" in C was
introduced for exactly this kind of symbolic values,
- Regarding the stdbool and stdint modules, I prefer an approach that
doesn't break unrelated platforms. We have already invested some effort
in these modules. I'm not interested in retesting it on platforms
from Linux libc5 to HP-UX 10 to BeOS.
