Unable to build for Python 3.13 on Linux

[pjyan]

python 3.13.0a3 gnureadline-8.1.2

As mentioned in https://github.com/python/cpython/issues/117669, _PyOS_ReadlineTState was removed from cpython 3.13

The error is

Hi, I'm currently busy making a new release that fixes issues with 3.12 and I decided to have a go at 3.13 as well. Unfortunately it's a bit too early... Tools like tox and pyenv are not quite up to speed yet, and there are many internal changes besides _PyOS_ReadlineTState. I'll wait until at least a beta release of 3.13 before I try again.

Thanks in advance. I guess there are not a lot of requirements for gnureadline based on 3.13 at this time...
