Yeah, that's a fair criticism.  I don't think we've tested that code
path since I retired prairiedog, so who's to say that it works even
now?  Maybe it's best to just delete that code, and if we ever find a
new platform with wider bool, figure out what to do at that time.

  1. Require sizeof(bool) == 1.

  2. If a C23 compiler is detected, try asking for C17.

  3. Fix C23 compiler warning

  4. Rename C23 keyword

  5. Assume that <stdbool.h> conforms to the C standard.

  6. Revise tree-walk APIs to improve spec compliance & silence warnings.
