[netCDF #QVU-411184]: Probable bug in netcdf-4.1.1

Hi Marica,

The default c++ interface provided with version 4.1.1 only supports
the older "classic" data model used in netCDF-3, not the "enhanced"
data model used with netCDF-4.  There is an experimental contributed
C++ library for netCDF-4 that's included with netCDF-4.1.1, but to
build and test it, you have to specify --enable-cxx-4 to the configure
script.  The documentation available for this new netCDF-4 C++
interface is available here:

  http://www.unidata.ucar.edu/software/netcdf/docs/cxx4/

I thought we had a pointer to this on our documentation page, but it
seems to have disappeared.  I'll see if I can get that added.  We
should be announcing this new C++ API, contributed by Lynton Appel of
the Culham Centre for Fusion Energy (CCFE) in Oxfordshire, soon.
