netcdf c++ on WinNT

new files are in ftp://ftp.unidata.ucar.edu/pub/netcdf/contrib/win32:

        netcdf-3.5.win32bin.ZIP         (lib/netcdfpps.lib)
        netcdf-3.5.win32make.ZIP        (cxx/msofts.mak)

note i only got the static version to work. if they need DLL version,
perhaps they can get that to work and tell us how.

I suspect its very simple, but i kept getting "unsatisfied externals" on
_ncerr and _ncopts during the dll link phase (see cxx/msoft.mak);
presumably it didnt load the netcdf.dll.
