Porting to Python 3.13
----------------------
* ``Python.h`` no longer includes the ``<ieeefp.h>`` standard header. It was
included for the ``finite()`` function which is now provided by the
``<math.h>`` header. It should now be included explicitly if needed. Remove
also the ``HAVE_IEEEFP_H`` macro.
