Misc/NEWS.d/next/Build/2021-10-11-16-27-38.bpo-45405.iSfdW5.rst

-Prevent ``internal configure error`` when running ``configure``
-with recent versions of non-Apple clang.  Patch by David Bohman.

Misc/NEWS.d/next/Build/2021-10-12-02-13-08.bpo-45440.-zYgDb.rst

-Building Python now requires a C99 ``<math.h>`` header file providing
-the following functions: ``copysign()``, ``hypot()``, ``isfinite()``,
-``isinf()``, ``isnan()``, ``round()``.
-Patch by Victor Stinner.

Misc/NEWS.d/next/Build/2021-10-18-10-25-56.bpo-45221.rnulhf.rst

-Fixed regression in handling of ``LDFLAGS`` and ``CPPFLAGS`` options
-where :meth:`argparse.parse_known_args` could interpret an option as
-one of the built-in command line argument, for example ``-h`` for help.

Misc/NEWS.d/next/Build/2021-10-20-12-42-39.bpo-45536.oQNYHB.rst

-The ``configure`` script now checks whether OpenSSL headers and libraries
-provide required APIs. Most common APIs are verified. The check detects
-outdated or missing OpenSSL. Failures do not stop configure.

Misc/NEWS.d/next/Build/2021-10-20-16-07-39.bpo-45532.kyhvis.rst

-Update :data:`sys.version` to use ``main`` as fallback information.
-Patch by Jeong YunWon.

Misc/NEWS.d/next/Build/2021-10-20-17-02-56.bpo-45548.BoggEf.rst

-Fill in missing entries in Modules/Setup.

Misc/NEWS.d/next/Build/2021-10-22-14-00-44.bpo-43974.HHZtbx.rst

-``setup.py`` no longer defines ``Py_BUILD_CORE_MODULE``. Instead every
-module, that uses the internal API, defines the macro.

Misc/NEWS.d/next/Build/2021-10-22-14-45-40.bpo-45570.61gM2A.rst

-:mod:`pyexpat` and :mod:`_elementtree` no longer define obsolete macros ``HAVE_EXPAT_CONFIG_H`` and ``USE_PYEXPAT_CAPI``. ``XML_POOR_ENTROPY`` is now defined in ``expat_config.h``.

Misc/NEWS.d/next/Build/2021-10-22-15-28-29.bpo-45571.yY8NsJ.rst

-``Modules/Setup`` now use ``PY_CFLAGS_NODIST`` instead of ``PY_CFLAGS`` to
-compile shared modules.

Misc/NEWS.d/next/Build/2021-10-24-11-02-43.bpo-45595.WI_5YU.rst

-``setup.py`` and ``makesetup`` now track build dependencies on all Python
-header files and module specific header files.

Misc/NEWS.d/next/Build/2021-10-24-21-49-49.bpo-45548.UWx0UC.rst

-The :mod:`math` and :mod:`cmath` implementation now require a C99 compatible
-``libm`` and no longer ship with workarounds for missing acosh, asinh, atanh,
-expm1, and log1p functions.

Misc/NEWS.d/next/Build/2021-10-28-14-47-22.bpo-45548.mdCBxB.rst

-``Modules/Setup`` and ``Modules/makesetup`` have been improved. The
-``Setup`` file now contains working rules for all extensions. Outdated
-comments have been removed. Rules defined by ``makesetup`` track
-dependencies correctly.

Misc/NEWS.d/next/Build/2021-10-29-12-54-53.bpo-45666.w2G63u.rst

Misc/NEWS.d/next/Build/2021-11-01-12-51-46.bpo-43158.fghS6w.rst

-``setup.py`` now uses values from configure script to build the ``_uuid``
-extension module. Configure now detects util-linux's ``libuuid``, too.

Misc/NEWS.d/next/C API/2021-05-24-22-12-40.bpo-44220.H9CUGl.rst

-:c:var:`PyStructSequence_UnnamedField` is added to the Stable ABI.

Misc/NEWS.d/next/C API/2021-09-24-11-12-21.bpo-43760.Bfxd1-.rst
