--- Comment #13 from Paolo Carlini <paolo.carlini at oracle dot com> ---
Excellent, that version is very safe. Are you willing to commit it? Otherwise,
I don't know when I can do it, maybe only Sunday. If you do that, you may want
to also add, after the first comment:

// By default follow the old inline rules to avoid ABI changes.

something like:

// (logic copied from libsupc++/typeinfo (libstdc++/61536)).

otherwise the patch is ready to go in.
