The reason for the above failure of the C++ compiler is in the file
"config.log":

This is a well-known problem.  The solution is to use the latest "beta"
version of the netCDF package (don't be put-off by the "beta" label).
This latest version can be found at

    <ftp://ftp.unidata.ucar.edu/pub/netcdf/netcdf-beta.tar.Z>
