> For third-party code, pyatomic.h is only needed by PyThreadState_GET() in pystate.h. Maybe we should hide completly pyatomic.h. Currently, pyatomic.h is not really used if Py_LIMITED_API is defined.
pystate_cplusplus.patch: disable completly pyatomic.h on C++, and modify pystate.h: PyThreadState_GET() is just an alias to PyThreadState_Get() with compiled with C++.
IMO pystate_cplusplus.patch makes more sense.
I don't understand the purpose of atomicfix.patch or pyatomic_cpp.patch, PyThreadState_GET() will not work with these patches.
