>From the Alpha Makefile.alpha:

CWARNFLAGS?=    -Werror -Wall -Wstrict-prototypes -Wmissing-prototypes \
                -Wno-format 

I don't see -Wno-unused, and I just fixed a whole bunch of 'unused'
lossaged in the MI kernel to allow NetBSD/alpha's kernel to compiler
without -O.  8-)

They're not (necessarily) kernel bugs, but -Wunused _has_ given me
useful information.  I mark any fixes that I make where gcc's
obviously wrong with "XXX gcc -Wunused".
