From 38c202df4db8eddd5e6f6f7d6506ce97912a3111 Mon Sep 17 00:00:00 2001
From: Dana Robinson <derobins@hdfgroup.org>
Date: Mon, 26 Nov 2018 22:10:06 -0800
Subject: [PATCH] Updated H5S to use the MPI-2 function MPI_Type_get_exten()
where available. OpenMPI 4.0 removed the deprecated MPI-1 MPI_type_extent()
call by default, so this avoids needing a special OpenMPI build.
