Fixed how?  It's not broken. :-)

We're compiling syscons.c with -Wunused and gcc, faithfully according
to instruction, is warning you about unused variables.  __unused
sounds kinda gross, but it's still worlds better than the /* WUNUSED*/
comments which were "magically understood" by lint, along with
/* NOTREACHED */.

It's just not possible to make the verifier flag these cases in a
"DWIM" fashion, since an intentional omission is indistinguishable
from a bug at that level, so you either don't ask for -Wunused
warnings or you give the compiler hints.  Seems reasonable to me!
