Build hygiene so the curses modules build against a limited curses (e.g. the native SVr4 curses of illumos/Solaris), matching how other optional functions are already gated: * Probe and #ifdef-gate the X/Open attr_t functions (window.attr_get/attr_set/ attr_on/attr_off/color_set), the soft-label attribute functions (slk_attr_on/off/set, slk_color) and scr_set(); scr_set is probed separately from the scr_dump family, which SVr4 has without it. * Stop gating update_lines_cols() on resizeterm(): it only reads LINES/COLS and is used unconditionally (e.g. by set_term()), so a build without resizeterm() failed to link. * On Solaris/illumos define _BOOL (and include <stdbool.h>) so the SVr4 <curses.h> "typedef char bool" does not clash with C's bool. test.test_curses: skip or guard the tests that use the now-optional functions, split test_attributes so its chtype-based part still runs, and treat the native curses of NetBSD and illumos/Solaris as having broken newterm() (they crash on repeated newterm()/delscreen(), like ncurses before 6.5).

The Python C API ================ The C API is divided into these sections: 1. ``Include/``: Limited API 2. ``Include/cpython/``: CPython implementation details 3. ``Include/cpython/``, names with the ``PyUnstable_`` prefix: API that can change between minor releases 4. ``Include/internal/``, and any name with ``_`` prefix: The internal API Information on changing the C API is available `in the developer guide`_ .. _in the developer guide: https://devguide.python.org/c-api/
