I guess the original reason for DUNE_THROW has been made obsolete (largely) by
the introduction of to_string() in C++11.  I'd still keep it around, however;
almost all dune code uses it and I don't see a good enough reason to change
it.

Also, I know of some modules from Mario's group that redefine DUNE_THROW to
include source location information, such things would be made harder if we
abandon DUNE_THROW.

Regards,
Jö.
