If I understand this discussion correctly that code that would be
conditionalized using this define is the IS_SELECTABLE macro in
selectmodule.c and very simular code in other modules. I'd say that
calling the test _Py_IS_SELECTABLE and putting it into pyport.h
as Tim mentioned in an aside seems to be a good solution. At the
very least it is a lot nicer than defining a very long name in
pyconfig.h and then having very simular code in several #if blocks.
