```

This is caused by the changed location of longintrepr. See https://docs.python.org/3.11/whatsnew/3.11.html and https://github.com/python/cpython/issues/79315

Inizia riproducendo la build con Python 3.11 e ispeziona http_parser/parser.c, la cui compilazione fallisce durante la build dell’estensione da setup.py. Controlla il cambiamento nella posizione degli header di Python 3.11 descritto nella documentazione collegata, quindi verifica che la wheel di http-parser venga compilata correttamente con Python 3.11 senza compromettere le versioni supportate precedenti.
