arrays. The MPI 3.0 standard added const to all in buffers in the C bindings. This commit adds the const keyword and in most cases casts const away. We will eventually should go through and update the various interfaces (coll, pml, io, etc) to take the const keyword. The group, comm, win, and datatype interfaces have been updated with const. cmr=v1.7.4:ticket=trac:3785:reviewer=jsquyres This commit was SVN r29266.
