1. Use pkg-config to check for ncursesw/panelw. If that fails, use pkg-config to check for ncurses/panel. 2. Regardless of pkg-config output, search for curses/panel headers, so we're sure we have all defines in pyconfig.h. 3. Regardless of pkg-config output, check if libncurses or libncursesw contains the 'initscr' symbol; if it does _and_ pkg-config failed earlier, add the resulting -llib linker option to CURSES_LIBS. Ditto for 'update_panels' and PANEL_LIBS. 4. Wrap the rest of the checks with WITH_SAVE_ENV and make sure we're using updated LIBS and CPPFLAGS for those. Add the PY_CHECK_CURSES convenience macro.

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. */
