   most platforms, but not on macOS. This is because, starting with Xcode 15,
   Apple-provided ncurses.h comes from ncurses 6 (which defaults to opaque
   structs) but can still be linked to older versions of ncurses dynamic
   libraries which don't provide functions such as is_pad() to deal with opaque
   structs. Setting NCURSES_OPAQUE to 0 is harmless in all ncurses releases to
   this date (provided that a thread-safe implementation is not required), but
   this might change in the future. This fix might become irrelevant once
   support for macOS 13 or earlier is dropped. */
