  I think that just when the ABI becomes backwardly incompatible would
be a very cruel moment to remove the support for keeping old installed
versions running.

  A fix would seem to be very simple, based either on detecting the
first numeric char in the version string and seeing if it's < or >= 3,
or perhaps just simply make it search for cpp0 first and if that fails
fall back on cpp.
