https://github.com/zsh-users/zsh/commit/4c89849c98172c951a9def3690e8647dae76308f
https://bugs.gentoo.org/919001
Avoid incompatible pointer types in terminfo global variable checks.
Some compilers reject these incompatible pointer types, causing the
checks to always fail, when these variables are in fact available.
