I have no objection to doing that in principle, but it basically means
programming effort in order to remove something, which I'm not happy about.
Hmm ... we'd have to drop eh_ptr.cc and exception_ptr.h completely for
that mode, and modify eh_throw.cc so that the cleanup function doesn't
use the reference counting. I think we can leave the other modifications
in; they don't affect the handling.
What macro do I switch on? _GLIBCXX_ATOMIC_BUILTINS_4?
