* gh-157695: Parse also _Py_HAVE_xxx variables in sysconfig (#158926) Add parse_config_h() tests to test_sysconfig. (cherry picked from commit978a8befa5) * gh-158893: Make os.strerror() thread-safe (#158927) Make os.strerror() thread-safe: use the reentrant strerror_r() function if available. * The configure script now checks if strerror_r() is supported. * Add a stress test to test_free_threading.test_os (new module). * Add a comment on decode_current_locale() assertion which fails if the input string is mutated. * Add an assertion to _Py_DecodeLocale() to detect if the input string was mutated during the function call. * gh-158893: Add internal _Py_strerror() function (#158982) Add a new internal _Py_strerror() function to Python/fileutils.c. It uses strerror_r() if available, or use strerror() otherwise. Replace all strerror(code) calls with _Py_strerror(code). (cherry picked from commit15dd7356f3)
