[Mpi-forum] how to get MPI::Exception behavior from C bindings?

Can someone explain how one can migrate (backwards) from the C++ to
the C bindings if they currently use MPI::Exception in a try-catch
block like this:

        try {
        catch (const MPI::Exception& e) {
            error("caught an MPI exception");

This is taken from MADNESS, btw.

I think it is only fair for those who want to kill the C++ bindings to
provide a clear description of how this will not break existing codes
that use C++ bindings.  Clearly, many things, e.g. MPI::BYTE ->
MPI_BYTE, are trivial, but I see error handling as being fundamentally
