I don't know how NetBSD deal with it.

My thought has always been that if it becomes too troublesome to
prevent people introducing fatal warnings on some architectures, we
can enable NO_WERROR for that arch.  This will also probably be needed
during the porting phase to new architectures which may produce
different kinds of gcc warnings.

I guess it's up to the alpha developers to decide if the rate of
warnings being introduced is annoying enough to warrant NO_WERROR on
their platform, or if it's better to just fix the (usually trivial)
warnings as they come up, so the code stays clean and portable and
doesn't get left behind.
