On the other hand, I find extremely difficult to spot whether a change
is architecture-specific.  Consider the reason IP_RECVERR breakage.  Not
having done any Darwin or Hurd development work, I had no idea that the
feature was missing there.

I don't want to make such changes because as far as I know, for some
contributors at least, we cannot legally remove them unilaterally
because these authors have a right to be named as such, something that
the FSF copyright assignment did not (and could not) take away from
them.
