So using GCC 16.

I did see some posts to gnulib recently re GCC 16 and language levels,
and also some recent gnulib tweaks re _Generic support,
so CC'ing gnulib.

Note coreutils 9.9 is using gnulib from Nov 2025.
It would be good to test if this is already addressed
with a gnulib (7606f1f2) from a couple of days ago using:

wget https://pixelbeat.org/cu/coreutils-9.9.192-6b32a.tar.xz
tar -xf coreutils-9.9.192-6b32a.tar.xz
cd coreutils-9.9.192-6b32a
./configure --quiet && make -j $(nproc)

thank you,
