 FWIW, plain INET6-less is ok.  as a consumer of this, i've
 helped keep it working.  i don't personally care about this
 case (no inet at all), but i support it working.

 these warnings are in 3rd party code we don't want to modify
 just to avoid a useless warning message.
 
 if they come up as "warning" not "error", that means we have
 explicitly chosen to ignore this verbosely.
 
 the warning-as-error in general is useful, but not for this
 specific case.  some we flat out disable or don't use.
