So my belief is that it is safe to drop those symbols from libstdc++.
Every program/DSO using them have to define its own copy of those

Really, you should check with Jakub before proceeding. I the change it's
Ok with him, it's Ok with me too (the other library maintainers should

If I can ask you a personal courtesy, please don't commit anything
causing regressions, like check_abi failing, either a complete change,
or nothing.
Thanks!
Paolo.
