Isn't -Wunused-but-set-variable enabled only for W=1 builds?

Maybe Bill's tree does not have commit 885480b08469 ("Makefile: Move
-Wno-unused-but-set-variable out of GCC only block"), which disables the
warning for clang just like GCC for regular builds?

Looks like 885480b08469, which landed in v5.13-rc1, so that's a
possibility. Should that be sent to stable@ so that we don't observe
these warnings for non-W=1 builds of stable branches with newer
versions of clang?

It is already in all supported stable versions.

Cheers,
Nathan
