IIRC the version of libstdc++ is tied to the GCC version so you'll
need that too. It is possible to install multiple versions of gcc side
by side ( e.g. https://aur.archlinux.org/packages/gcc46/ )

But I would like to suggest two alternatives.

* Have you tried using clang instead (available in "extra")?
* You could also compile the binaries on a different machine (be
careful to compile for the right architecture) and copy them to your
i686 machine
