Thanks, that workaround is much better for coreutils, and I installed it here:
https://git.savannah.gnu.org/cgit/coreutils.git/commit/?id=f6cb50cc991d461f443ea3afc517c9e1e37ef496

--- Comment #3 from Martin Sebor ---
I agree that's not an improvement. Would something like this be better? (at
least until utmp_ent is marked nonstring and GCC taught to suppress the
diagnostic)
size_t utmpsize = sizeof UT_ID (utmp_ent);
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85602
--- Comment #2 from Paul Eggert ---
Thanks for looking into it. For what it's worth, the practical effect of this
new warning was that I changed that part of coreutils to not use strncat,
causing 3 lines of code to grow to 8 lines. See the end
