Is it the case? Is the above enough for that? Or some of the changes which went in are effective anyway even if __cplusplus is reverted by hand to 1? I think this is the question deciding what we really want to do.
I'm pretty sure this is the case for Solaris. The other changes we've
made to support __cplusplus 199711L were no-ops without the last one to
change __cplusplus from 1 to the C++ 98 value. So, redefining
__cplusplus to 1 should return us back to the old status.
