[New-bugs-announce] [issue13338] Not all enumerations used in _Py_ANNOTATE_MEMORY_ORDER

Hi,

When compiling using gcc and -Werror=switch-enum the compilation fails, e.g. while compiling an extension module:

In file included from /usr/include/python3.2mu/Python.h:52:0,
                 from src/util.c:27:
/usr/include/python3.2mu/pyatomic.h: In function ‘_Py_ANNOTATE_MEMORY_ORDER’:
/usr/include/python3.2mu/pyatomic.h:61:5: error: enumeration value ‘_Py_memory_order_relaxed’ not handled in switch [-Werror=switch-enum]
/usr/include/python3.2mu/pyatomic.h:61:5: error: enumeration value ‘_Py_memory_order_acquire’ not handled in switch [-Werror=switch-enum]
/usr/include/python3.2mu/pyatomic.h:70:5: error: enumeration value ‘_Py_memory_order_relaxed’ not handled in switch [-Werror=switch-enum]
/usr/include/python3.2mu/pyatomic.h:70:5: error: enumeration value ‘_Py_memory_order_release’ not handled in switch [-Werror=switch-enum]

This could be easily resolved without any drawbacks by simply listing the missing enumeration items together with the default.  And that would enable extensions to be built using -Werror=switch-enum again.

Regards,
Floris
