I don't think we really want lots of unused variables being assigned
to, do we ?  In some cases the function computing the value may be
doing pointless work and so this might even improve performance.

So I think -Wset-but-unused-variable is fine with -Werror too in the
long run but we'll have to have it with
-Wno-error-set-but-unused-variable (or whatever the syntax is) until
the compiler becomes widespread.
