Reducing the warnings to one warning per module might be reasonable.
To silence the warning, you should really add "L" suffixes to all
those literals - or we could provide a future statement, where you
indicate that you want those literals to become positive longs *now*;
you'ld need to add this statement once per module.
However, when you do that, I believe you will get OverflowErrors
once you pass the constants to your C API.

Feel free to propose specific patches. I believe this specific
strategy is unimplementable: When the value goes to ParseTuple, it is
not known anymore whether the integer literal was hex (or whether
there was any integer literal at all).
