Hi!

While rebuilding the python related packages against the Python 3.15rc1
version we found that pygame fails to build from source [1].

Sadly, the upstream repository seems to be abandoned. I found that the
Fedora team had already made a patch for fixing this issue [2] and
reported it upstream [3].

However, that patch was causing some tests to fail (and it seemed like a
legitimate failure, due to a bug in the patch), so I've adapted it to
make it work correctly.

While doing this, I also found the reason for one of the reference
counting errors that were being hard-fixed for 3.14+ inside of
py314-refcount-tests.patch, and added a patch that fixes the test to
make it behave correctly instead.

I applied these fixes in the sandbox [4] to be able to build the
packages that depend on pygame, please consider applying the patch to
support the upcoming 3.15 version.

Happy hacking,
