Yeah, this is a complicated example, mostly because HDF5 should
really be covering this problem for you. I think your only option at
that point would be to use the #define to not include the C++ code.
The problem is that the MPI standard *requires* mpi.h to include both
the C and C++ interface declarations if you're using C++. There's no
way for the preprocessor to determine whether there's a currently
active extern "C" block, so there's really not much we can do. Best
hope would be to get the HDF5 guys to properly protect their code
