In the weekly CI, I see a test failure: FAIL: test-nstrftime-2.sh on NetBSD 10, Solaris 11.4, and Solaris 11 OmniOS, that was a PASS last week.
Since nothing in this area has changed in Gnulib since last week, I suspect that the cause is the diffutils commit 25919920377f08d6f09df804c7f8af11f5adaabe diff: reduce nstrftime dependency The obvious workaround will be to change bootstrap.conf, adding a gnulib-tool option --avoid=nstrftime-tests .
