This one is actually really funny. The function MPI_Register_datarep
is defined in the mpi.c as {extern "C"}. As some of the arguments are
pointers to function, they automatically become typed as {extern "C"}.
But in the Cxx interface, the arguments are not types as {extern "C"}
which trigger the compiler warning.
I don't think it is necessary to fix this, as the callback functions
should not be types as {extern "C"}. The compiler is a little too
cautious.
