While doing that, beware that gcc has bugs causing some ports (I
forgot which ones) to get at least one spurious warning
apparently not attributable to the quality of the port.

PR(s) duly entered, but I can't quote the numbers (finding PRs
is not practical for me after the https change, but IIRC Joern
was the author).

PS. of course no excuse to not get the low-hanging fruit.
