Huh?  Filtering _would_ fix the original problem of getting wrong
configure results under -Werror, because -Werror wouldn't be used during
configure.  It's just a question of whether it is safe to filter by
default, or whether filtering is enough of a change to require a
one-line addition to configure.ac explicitly requesting the filtering.
