[Navier-Stokes] Remove operators in dune-funcep as workaround because of g++-4.9 bugginess
The Navier-Stokes local operators in PDELab access the childs in the grid function space with the integral constants _0
and _1
respectively. This doesn't compile with g++-4.9 due to a bug. Therefore versions of the operator in dune-funcep are created where _0
is replaced by 0
etc.
Once a newer version of g++ is installed in the computer pool, these workarounds can be deprecated and then removed.
