[mpich2-dev] [mpich-discuss] Overflow in MPI_Aint

[Pavan Balaji]

Hi Joe,

I tried to extract the code change portions from the patch you sent, but 
that doesn't seem to be easy (the patch seems to show many changes to 
the docs and other such files which have not changed for a long time). 
Is there a way for me to get the code changes, either from this patch, 
or by exporting from some git branch?
