While starting to port the Python Sybase module to Python 3, among other hurdles, I noticed that RO is no longer defined. Looking in structmember.h, I see that most of the macros defined there are missing a PY prefix. Given that these are macros which are likely to be used by extension modules and are thus really part of the C API, shouldn't they have PY or PY prefixes? This file got its start in 1990, so would surely have been around for the great renaming <http://python-history.blogspot.com/2009/03/great-or-grand-renaming.html>. Looking at the documentation on defining new types, I saw no mention of these peculiarly named constants, though they are clearly documented.

structmember.h is not included in Python.h. I think it was not considered as the part of public C API.

But PyMemberDef and constants are documented and structmember.h is used in C API examples.

There are other problems with these constants. Opened an issue for this: http://bugs.python.org/issue28349 .
