Projects not using pythoncapi_compat.h
======================================
Projects not using ``pythoncapi_compat.h``:
* numpy has its own compatibility layer, ``npy_pycompat.h`` and
``npy_3kcompat.h`` header files. It supports more C compilers than
pythoncapi_compat.h: it supports ``__STRICT_ANSI__`` (ISO C90) for example.
Rejected `PR 18713: MAINT: Use pythoncapi_compat.h in npy_3kcompat.h
<https://github.com/numpy/numpy/pull/18713>`_ (when it was rejected, numpy
still had code for compatibility with Python 2.7).
* Cython doesn't use pythoncapi_compat.h:
`see Cython issue #3934
<https://github.com/cython/cython/issues/3934>`_.
For example, `ModuleSetupCode.c
<https://github.com/cython/cython/blob/0.29.x/Cython/Utility/ModuleSetupCode.c>`_
provides functions like ``__Pyx_SET_REFCNT()``.
Project with a strict contributor agreement:
* `zodbpickle
<https://github.com/zopefoundation/zodbpickle/pull/64>`_
