Msys2-next after 210831
I'm currently compressing an environment snapshot from yesterday (211115). Initial patch for using it attached here.
For next couple of days I will be testing that various builds can be made with it, and also smoke testing that produced programs work (at least launch). I will upload it once it has passed these tests.
Existing builds work. Environment uploaded. Review period for this patch begins.
For the next msys2 snapshot I'm about to add gtk4 libraries for enabling freeciv windows installer development against them. It should be possible to update sdl2-client installer to use gtk4 modpack installer once the libraries are available.
As we found out in #42343, Qt6 is not co-installable with Qt5 in msys2 and as we will need Qt5 for some time (to make it possible to backport new msys2 environment to S3_0), we can't have Qt6 in the official snapshot.
As part of #43200, this has also been posted to http://forum.freeciv.org/f/viewtopic.php?f=14&t=92043
