The netCDF Fortran functions call the C functions rather then the C++
functions.  If any of our documentation implies that the Fortran
interface for netCDF uses the C++ interface rather than the C interface,
I'd like to know about it so I can correct the documentation.

I don't know much about how to call C++ functions from Fortran.  As far
as I know, there is no standard for a Fortran/C++ interface that vendors
follow, so any solution would be platform-specific.  I think it would be
more difficult than calling C from Fortran, which is already non-trivial
(we use a solution developed at CERN known as "cfortran.h", but it's not
entirely satisfactory).
