Not really. It even has the same homepage (or rather has not anymore).

I wonder, why there hasn't been any new release despite the activity in 
the repository (for both tommath and tomsfastmath).

of new upstream releases in the future.

We don't use the embedded ltdl, but clamav uses the system version on 
its own, unless configured with --with-included-ltdl.
