Is this still a problem or can the issue be closed?

The define in question by that name still exists in token.h in 3.x. I've added srid to nosy since as an AIX user he probably knows if this is a real problem or not, and Benjamin because he's done a lot with the parser.

I can confirm that this problem is still present with Python 3.1.2 on AIX 6.1. This is just a compilation warning, but the patch in
msg110771 correctly cleans it.
