Thank you for feedback but unfortunately it is not the info that helps.
It appears exactly the problem as mentioned in Etc/MACHINES - when
configure tests for boolcodes & Co it does not find them  (because they
are missing in library or at least not exported) so it decides to use
local versions. And this clashes with declaration in term.h. What was
meant was some hint how to detect this condition.

Proper way to fix it would be

- use something like _zsh_boolcodes internally
- check for both declaration and availablility
- on well-behaving systems simply do #define _zsh_boolcodes boolcodes
- on bad systems leave _zsh_boolcodes as local definition.

Unfortunately (proper) test for declaration is missing in autoconf 2.13
and honestly speaking I am reluctant to backport it from autoconf 2.5x.
If anybody feels like doing it - he is welcome.

And I know that current 4.0 maintainer is reluctant to forget 2.13
compatibility :-)

_PLEASE_ next time when you send 1000+ lines to list at least compress
them. Much better is first ask if this is really needed.
