--- Comment #4 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Some programs which happen to not use any new features might work with an older
version of libstdc++.so but that is not guaranteed, and definitely not
supported.

Removing one or two functions from a header is not going to solve the problem
in the general case. Using _GLIBCXX_USE_CXX11_ABI is also not a solution for
this, that's not what it's for.

If you want to run with the libstdc++.so from GCC 4.9.4 then compile with GCC
4.9.4, that's guaranteed to work.
