As soon as anythin in the final executable links against MPI, the binary must
call MPI_Init().  libdunegrid will link against MPI

 - if it was built with ALUGrid and ALUGrid links against MPI, or
 - if it was built with UGGrid and UGGrid links against MPI.

All the non-ALU, non-UG MPI-dependent code is headers only, so it's possible
to decide based on defined whether MPI is actually used or all calls to MPI
functions are replaced by dummys.

I guess this is another reason for dune-alugrid and dune-uggrid.

Bye,
Jö.

If you receive something that says "Send this to everyone you know,"
pretend you don't know me.
