[netCDF #ISQ-236686]: configure script for netcdf-fortran package does not support netcdf4 nicely

The 4.4.2. version of the Fortran configure script is designed to detect 
whether the netCDF C library supports netCDF-4 and build the Fortran API 
appropriately.

That's the way it works for us on Linux and OSX platforms, but we don't have an 
HPUX platform on which to test it.

For that to work, you need to specify where the netCDF-C library was installed 
exactly as these instructions specify:

  http://www.unidata.ucar.edu/netcdf/docs/building_netcdf_fortran.html

If you follow those instructions and it doesn't work for HPUX, we'd like to 
know about it.

That's great, congratulations, but we would like to know whether it also works 
the way we have documented and tested it on other platforms.
