That would be nice to have, but I don't have the bandwidth to handle this goal.

Last years, I tried to fix a few integer downcast warnings on Windows
64-bit, but they are still a few ones. It's not easy to distinguish
warnings from real bugs (integer overflow).

There are a few open issues about Windows 64-bit warnings.

Segev Finer just wrote an interesting but big PR:
https://github.com/python/cpython/pull/2492

The deprecated warnings is another interesting topic :-)

My policy is more to start by fixing all warnings, before starting to
check for regressions.

I began by fixing the most common test failures, then references
leaks, and now memory leaks. So it becomes much simpler to check for
regressions on these checks.
