new libstdc++-v3 decimal failures

[Benjamin Kosnik]

Why do we have a libstdc++ list? For questions like this...

...means that it's the excess error that is the fail. Not the error.

On the brightside, the error is better now, I think.

I changed this from what Janis posted, so she is certainly not to blame
here. In any case, all you should have to do is add a new line for this
new error:
