TWIMC, there is another report about this in this thread (sadly some of its post did not make it to lore):
https://lore.kernel.org/all/162ef3c0-1d7b-4220-a21f-b0008657f8a5@redhat.com/
Ciao, Thorsten

This doesn't fail on x86-64 when I build it. I also did a cross-compile to arm64 with the arm64 defconfig, and it doesn't fail there either.
I'm guessing this is a compiler version thing. I'm using gcc 11.4. Is that just too old?

It's too new: this is valid syntax in c23 and accepted by newer compilers as an extension to gnu11, but older versions don't like it.
gcc-11 and clang-16 are fine, while gcc-10 and clang-15 as well as earlier versions produce this warning.
