From: Colin Watson Date: Thu, 11 Dec 2025 11:23:06 +0000 Subject: Fix Cython build with Python 3.14 As described in https://bugs.debian.org/1122023, the Cython build fails with Python 3.14. This is similar to #23; it has come back because Python 3.14 changed the default start method to `forkserver`, which has similar properties to `spawn` in this area. Rather than continuing to play whack-a-mole by special-casing more start methods, it's better to take the approach suggested in https://github.com/akornatskyy/wheezy.template/issues/23#issuecomment-737210953 and move most of `setup.py` into a function.
