[Dune] problems with dune-functions building

[Christoph Grüninger]

Hi Francesco,
I don't know an answer to your problem, but I recognize the 
error.
I did not yet find the time to pinpoint the problem. I switch 
to
the compiler, from Clang or GCC or the other way round.
I suspect a bad combination of Compiler and default includes.

Note that I am not using dune-functions but PDELab.

Bye
Christoph
