uvloop fails to build with Python 3.13.0a5: error: implicit declaration of function ‘_Py_RestoreSignals’

uvloop version: 0.19.0
Python version: 3.13.0a5
Platform: Fedora Linux 41
Can you reproduce the bug with PYTHONASYNCIODEBUG in env?: n/a
Does uvloop behave differently from vanilla asyncio? How?: n/a

I try to build uvloop for Fedora Linux 41 with Python 3.13.0a5.
The build fails with the information below.

  uvloop/loop.c: In function ‘__pyx_f_6uvloop_4loop_9UVProcess__after_fork’:
  uvloop/loop.c:129617:5: error: implicit declaration of function ‘_Py_RestoreSignals’ [-Werror=implicit-function-declaration]
  129617 |     _Py_RestoreSignals();
         |     ^~~~~~~~~~~~~~~~~~

_Py_RestoreSignals() has apparently been moved to internal CPython: python/cpython@c9ce983

https://github.com/python/cpython/blob/v3.13.0a6/Modules/signalmodule.c#L1931-L1951

Maybe this can be inlined?

This one is a warning here on a pyenv-installed 3.13.0b1 (not sure if -Werror=implicit-function-declaration in the original report comes from Fedora defaults or what), but there are multiple actual errors:

      uvloop/loop.c:4446:105: error: invalid type argument of ‘->’ (have ‘int’)
