That's pretty scary in itself, since it suggests that the Python guys
know or think that changing those values will do something magic.
I'm worried that they are trying to do the same kind of thing that
we are trying to do with our put-postgres.h-first rule, namely ensure
that all loadable modules match the core's idea of libc properties.
If that's what's going on here, and their idea of those properties
is different from our standard build, then we may have worse problems
than a compiler warning.
