--- Comment #14 from Oliver Schönrock <oschonrock at gmail dot com> ---
I compiled gcc15 from the AUR

$ gcc-15 --version
gcc-15 (GCC) 15.2.1 20260209

and can confirm that neither the 3TU nor the 1TU version emits the diagnostic. 

I will attach the preprocessed source for the gcc15 1TU version, which is
obviously quite different.
