Sneaky C++11 syntax broke fenicstools

Just wanted to report that my interpolation code in fenicstools now is broken with the instant compile log extract:

In file included from ../../../home/mikael/Fenics/bitbucket/dolfin/local.master/include/dolfin/la/dolfin_la.h:68:0,
                 from ../../../home/mikael/Fenics/bitbucket/dolfin/local.master/include/dolfin.h:21,

     ^

       solver->update_parameters(parameters);
       ^

I report it here since the error originates from apparently experimental code in dolfin. Is there an obvious easy fix or should I get back with more details?
