I'm all for the C module exposing any and all of the S_* macros for
the local platform, and good with the python module (if used because
the C module isn't present, or conceivably is compiled out because
it is known broken on this platform) exposing only the portable
stuff.

At least you can detect "I don't know what to do" rather than
ploughing on mistakenly.
