[boost] [bigint] Integer data type larger than 64 bits?

I have encountered the need for an integer data type larger than 64 bits
to prevent overflow when doing algebra on 32 bit integer data.  I notice
that there is mention of a couple proposed boost big int libraries in
the archive.  Is there a boost library that provides this currently, or
is there a library nearing acceptance level quality that I should use?
I am not eager to take on a non-boost/non-stl dependency because I
intend to submit the geometry library I need this for to boost.

Thanks,
Luke
