To build with parallel I/O requires hdf5 to be built with parallel

We are currently packaging the soon to be released netcdf v4.3.3,
and I can see that netcdf (~rc3) is now detecting parallel
automatically during the build.
After the recent discussion with the HDF5 maintainer, it became clear
that we cannot build netcdf with the HDF5 MPI variant only, we must
also build with the HDF5 serial variant for non-MPI applications.
Because we are under pressure to get the new netcdf packages ready for
the transition (#791215), I've reverted back to build netcdf with only
the HDF5 serial variant. After the GCC 5 related transitions, we'll
update the netcdf package to provide a netcdf library built with the
HDF5 MPI variant in addition to the serial variant.
Adding an MPI variant of NetCDF is not going to happen any time soon. It
requires extensive patching of both the Autotools & CMake buildsystems
to be acceptable for inclusion upstream.
As the only active maintainer of the netcdf packages in Debian, I'm
tempted to close this issue as wontfix because I'm won't be adding
support for the MPI variant in the foreseeable future.
I'm leaving this issue open for now, because I know some others did have
work in progress. But I will close it if there is no progress a year
from now.
