At a first guess, it looks as if you're mixing versions of GCC and
libstdc++.  Please post the following:

* List of packages you downloaded and installed
* Output of a compile, using the `-v' option
* Contents of your environment (output of SET)
* Any deviations you've made from the installation directions in
README.1ST
* Anything else you think relevant
