\subhead{Notes}
These are needed for implementing {\tt MPI{\tt \char`\_}Accumulate}, since only predefined
operations are allowed for that operation.
\par
A gap in the enum values was made allow additional predefined operations
to be inserted.  This might include future additions to MPI or experimental
extensions (such as a Read-Modify-Write operation).
