Sean and I have mixed feelings about this as well. There's been plenty
of "YES, I know that variable's unused, I just haven't gotten around to
it!" On the other hand, things such as passing a 'struct foo*' to a
function that expects a 'struct bar*' is only considered worth a
warning, while I think it definitely deserves an error.
For the specific case of unused variables (whose warnings are generated
by -Wextra) we could make a way to disable -Wextra or -Werror with
options to make (e.g. make WERROR=false WEXTRA=false) with the default
being to enable them. Do you think that this would help?
