[svn-r4732]
Purpose:
Bug Fix
Description:
Committing the changes in the MPI/IO stuff so that parallel HDF5
will work on HP-UX. It seems that on HP-UX, the MPI_Status variable
needs to be initialized to 0 for it to work (i.e., in some other MPI
calls, if there's garbage in the MPI_Status variable, then it will
barf).
Solution:
Initialized to 0.
Platforms tested:
HP-UX parallel, Linux.
