I bisected between

    commit 9ade7ea7b77ec40c16deb4dff139ce7127a703e2 (HEAD -> master, origin/master, origin/HEAD)
    Author: João Távora <joaotavora@gmail.com>
    Date:   Fri Jul 10 01:47:10 2020 +0100

and

    commit 7c7ee1dd52239ecc3665b7542bd5e0ebc9b74795 (grafted, HEAD)
    Author: Glenn Morris <rgm@gnu.org>
    Date:   Mon Apr 29 09:12:53 2019 -0700

and the commit mentioned in my report introduced the problem.  (Note
that the following commit 3f9d96e3d made it compilable.)

Tschö,
Torsten.
