Huh, so we have C for cross-builds and C++ for bootstraps.  I
wish we could retire that difference *also* on the 4.7 branch
(using either C *or* C++ for *both* would be fine with me FWIW).
I believe we're now eperiencing more problems than benefits with
that difference, now that the migration is over.

Sorry, not at the moment, but I see Janus took care of that
(thanks) and it looks pretty obvious to me.  It'll be noticed
when it's committed...
