Following up on that suggestion: The positive thing to report is "make deb"
gave a list of a half-dozen package dependencies that weren't installed; a
list that worked cleanly with apt install. This hadn't happened with 3.25,
so a good improvement.

The misfortune is that, when invoked after that, it churns through part of
the build only to stop at:

Would not treating warnings as errors get around that? Or is it something
more? I'm hesitant to change things naively, as I want a stable program to
result.

Thanks again for the help so far,
