The required functions are part of the netCDF-2 F77 interface.  I believe
they are in either win32-bin/netcdf.lib or win32-bin/netcdf.dll.  As it 
says in our FAQ:

  NOTE: User Viet Eitner has contributed a port of 4.1.1 to Visual
  Studio, including an F90 port to Intel Fortran. Download source
  
(ftp://ftp.unidata.ucar.edu/pub/netcdf/contrib/win32/netcdf-4.1.1-win32-src.zip)
  or binary
  
(ftp://ftp.unidata.ucar.edu/pub/netcdf/contrib/win32/netcdf-4.1.1-win32-bin.zip)
  versions. This port was done before the code was refactored in
  4.1.2.

so we didn't write the modifications needed for Windows Visual Studio and
don't have the resources to support contributed software like this.  We
make it available in the hope that it will be useful, but for detailed
questions about it, you may have to contact the developer who created and
contributed it.

Another possibility would be to just compile the library functions you need from
the source, in the netcdf-4.1.1/fortran/fort-v2compat.c file.

Sorry I can't be of more help, but the Windows development for netCDF is on 
hold until we have more time and resources, as explained here:

  http://www.unidata.ucar.edu/netcdf/docs/faq.html#windows_netcdf4_1

The gennet.f program is another user-contributed program that we make 
available, but don't maintain or support at Unidata.  I don't have an
email address that works for Barry Schwartz, unfortunately.
