Since this is a regression from MPI 2.0, I think we need to fix this. I do<BR>
not see a reason why we should not be able to fix these errors before the<BR>
final vote. Is there someone that disagrees with this ?<BR>

Subject: [mpi-21] A couple of bugs in 2.1<BR>
<BR>
I found a couple of bugs in MPI 2.1:<BR>
<BR>
* pg 332, ln 16-21: "MPI_REPLACE, like the other predefined operations, is<BR>
defined only for the predefined MPI datatypes. Rationale: The rationale for<BR>
this is that, for consistency, MPI_REPLACE should have the same limitations<BR>
as the other operations. Extending it to all datatypes doesn't provide any<BR>
real benefit."<BR>
<BR>
<BR>
That is not true. Derived datatypes are allowed in MPI_Accumulate for the<BR>
predefined reduction operations as explained in the paragraph just above it.<BR>
<BR>
<BR>
* pg 237, line 1 and line 3: MPI_MAX_OBJECT should be MPI_MAX_OBJECT_NAME.<BR>
<BR>
Accordingly, the Change Log needs to be updated for both these items.<BR>
<BR>
The question is can these be fixed before the 2nd vote in Sept.? My<BR>
understanding of the voting process is that the reason for having two<BR>
separate votes in two separate meetings is to have a chance to catch such<BR>
bugs. So it should be fixable. (Otherwise, what is the use of the 2nd vote?)<BR>
