[pyqtdeploy] Failing at building the demo

Fri Mar 8 18:21:39 GMT 2024

With C++ the relevant error is the first error line, the rest is usually
noise. If you google gcc numeric_limits is not a class template you will
find https://bugs.gentoo.org/768342

If you use gcc 11 then use gcc 10 otherwise patch qt headers as in
