Description
mpitraits.hh forward declares std::pair, which is illegal by the standard (it is not allowed to forward declare any members of namespace std), and clang (more precisely: its standard library implementation) stumbles over that.
The attached patch fixes the problem by including and dropping the forward declaration.
