I wonder whether g++-5 should artificially bump the minimum dependency version for libstdc++6, so that *everything* built with libstdc++6 picks up the (>= 5) dependency? Yes, that'll mean rebuilt packages can't transition until libstdc++6 does, which is why it is normally undesired (hence symbols files); but in practice it seems a reasonable number of e.g. KDE packages that are transitioning are broken anyway. It would certainly make the transition easier to track. S
