There are quite a few more instances of such errors across the source
code, the attached patch should fix all of them. The package builds and
from a cursory look appears to work, but it would be good if a potential
NMU'er reviews and tests the patch before uploading.

Subject: [PATCH] Avoid accessing internal ncurses structures
Since ncurses patchlevel 20231021 the WINDOW structure is opaque, its
members cannot be addressed directly. Use the functions ncurses
provides for this purpose instead.
