Compiling code using PythonQt release 3.4.1 on Rocky Linux 9.2 with Python 3.9 gives the following compile error:
/usr/include/python3.9/pythread.h:136:5: error: #error "Require native threads. See https://bugs.python.org/issue31370"
136 | # error "Require native threads. See https://bugs.python.org/issue31370"

/usr/include/python3.9/pythread.h:145:5: error: ‘NATIVE_TSS_KEY_T’ does not name a type
145 | NATIVE_TSS_KEY_T _key;
| ^~~~~~~~~~~~~~~~
By commenting out the #undef of _POSIX_THREADS (hence keeping _POSIX_THREADS defined) in src/PythonQtPythonInclude.h it builds and works fine.
$ cat /etc/redhat-release

Otherwise release 3.4.1 is working fine (without bespoke fixes/patches) for me now on CentOS 7 (Python 2.7), Rocky 8 (Python 3.6), Rocky 9 (Python 3.9), Ubuntu 20.04 LTS (Python 3.8), and Ubuntu 22.04 LTS (Python 3.10).
Only Python 3.8+ builds are affected by the _POSIX_THREADS issue so that also includes Ubuntu 22.04 LTS (Python 3.10) and Ubuntu 20.04 LTS (Python 3.8) in addition to Rocky 9 (Python 3.9). On all three platforms, not undefining _POSIX_THREADS solves the issue.
