https://bugs.freebsd.org/271047 is the exp-run bug for that; it will
depend on how much ports fallout there is, and the effort required to
fix things. Last time with clang 15 it took quite a while, but I hope it
may be somewhat easier this time.

For now it looks like the most impactful change is the new default of
-std=gnu++17 for C++ mode (like gcc >= 11), since C++17 has actively
removed a bunch of things which were deprecated before, for example the
'register' keyword. That tends to break older software, or software
which isn't updated very often.
