Description changed by mascguy:

Old description:

> Tracking ticket for port failures, caused by the introduction of
> `clang-15` as a default compiler.
>
> First known casualty: Inkscape
>
> Unfortunately I do not have the time to support yet another Clang
> version. So someone else will need to investigate and fix these, as I'm
> out.

New description:

 Tracking ticket for build failures, when `clang-15` is in play. The vast
 majority of these are likely to be legitimate code issues, caught by
 stricter validation checks, and/or standards evolution.

 However, we may occasionally encounter a legitimate compiler bug. And
 we'll want to report those to upstream.
