Some curses functions were removed in 3.12 for macos

[sobolevn]

These two functions are under #ifdef HAVE_NCURSESW macro:

#ifdefHAVE_NCURSESW/*[clinic input]_curses.unget_wch ch: object /Push ch so the next get_wch() will return it.[clinic start generated code]*/staticPyObject*_curses_unget_wch(PyObject*module, PyObject*ch) /*[clinic end generated code: output=1974c9fb01d37863 input=0d56dc65a46feebb]*/{wchar_twch; PyCursesInitialised; if (!PyCurses_ConvertToWchar_t(ch, &wch)) returnNULL; returnPyCursesCheckERR(unget_wch(wch), "unget_wch")} #endif

Which is set via configure:

iftest"$ac_sys_system"!="Darwin"; thendnlOnmacOS, thereisnoseparate /usr/lib/libncurseswnorlibpanelw. PKG_CHECK_MODULES([CURSES], [ncursesw], [ AC_DEFINE([HAVE_NCURSESW], [1]) have_curses=ncursesw ], [ WITH_SAVE_ENV([ AC_CHECK_LIB([ncursesw], [initscr], [ AC_DEFINE([HAVE_NCURSESW], [1]) have_curses=ncurseswCURSES_CFLAGS=${CURSES_CFLAGS-""} CURSES_LIBS=${CURSES_LIBS-"-lncursesw"} ]) ]) ]) fi

It says that macos is not supported anymore.
