Msys2-next after 210515
Apparently qt5 and qt6 are not coinstallable in msys2.
- Environment 210831 uploaded - Updated patch attached to this ticket
- Instead of updating setup-msys2 to a version that still is insufficient, disable the msys2 CI build. Patch for that attached.
For the next msys2 snapshot I'm going to at least evaluate gtk4 and Qt6 support.
There's also a new upstream base-snapshot 20210419.
