This is outside our library. I noticed them too. We cannot easily avoid 
these warnings. We could if we would not use ublas (which is indeed the 
plan, if we have proper replacement...).

You might contact the ublas team.

Or, actually, we could avoid them using a #pragma as done for MSVC too, 
occasionally. clang apparently supports that. I will look at that - that 
way is quite easy.

Thanks, Barend
