You can't; they're internal to GCC and its libraries.  I assume you are
using GCC 2.8.1; you *have* to link with libstdcxx, because that's where
these are defined.  Use the `gxx' command to link, and all should work.

You can read the source code for libstdc++, but it probably won't be
enlightening.
