Fails to build on Python 3.11 - longintrepr.h: No such file or directory

[ogajduse]

Bug report

Steps to reproduce:

1, dnf install python3.11-devel
2. mkvirtualenv ssh2-python-py311 --py 3.11 && workon ssh2-python-py311
3. pip install ssh2-python

Expected behaviour: ssh2-python should be installable on Python 3.11

Actual behaviour: Installation does not succeed, gcc throws an error.

Additional info:
ssh2-python-0.27.0
python3.11-devel-3.11.0~b3-1.fc35.x86_64
cmake-3.22.2-1.fc35.x86_64
gcc (GCC) 11.2.1 20211203 (Red Hat 11.2.1-7)

Seems that not only this package is affected by this issue, see aio-libs/aiohttp#6600

Hi there,

Thanks for the interest and report.

Development versions of Python are not supported. Support will be offered once 3.11 is released.
