Thanks for figuring that out.   The downcasts make it build with gcc
12.5.0.  I submitted a PR, which Nyall munged and merged.

I've updated pkgsrc-wip to 7d2ca374f2db34eef5b433d9dbf46ae894ada937.
pkgsrc is missing a few qt6 packages, but it builds and packages, and I
can open a project and things seem normal.

There is a complaint about authentication, which is almost certainly
about qgis not reaching the keyring daemon.  That works with the 3.44
package, and I'll look into it.

I have two patches to validate and maybe submit, both minor.

Overall, master heading to 4 is in remarkably good shape for my system,
and I think the remaining issues are mostly getting more qt6-foo
packaged.
