As we just found out on IRC when Heiko ran into the above failures when
compiling cli_ure/source/climaker/climaker_app.cxx, this apparently also
affects old versions of VS 2022, not just VS 2019:
Okt 05 14:58:32 <sberg> htietze, (1) what exact version of MSVC are you
using? (2) show a useful tail of your log, not just a single line
Okt 05 15:01:50 <htietze> 10.0.40219 MSVC++ 2010 (according the apps info)
Okt 05 15:02:11 <htietze> and 14.30.30704 2015-2022
Okt 05 15:03:12 <htietze> VS Build Tools 2022 / 17.7.4
Okt 05 15:04:50 <sberg> htietze, according to
<https://en.wikipedia.org/wiki/Microsoft_Visual_C%2B%2B#Internal_version_numbering>, "14.30" probably
means "Visual Studio 2022 version 17.0.1"; can you update to the latest version of "Visual Studio
2022" please?

Okt 05 16:35:05 <htietze> sberg: Build seems to work again after updating VS to
17.7.4. Thanks for the help.
