That's because #2 is so awful.  Here's a more reasonable alternative

3. Change just the offending constants by adding an "MPI_" prefix.  Of
course, this makes the constants the same as the C versions, which doesn't
seem so bad.  That really makes the choices these:

1. Change to lowercase.

4. Remove them and use the respective C versions (MPI_SEEK_SET etc.)

I'd prefer 4 slightly over 1.
