Hi Steve,

With gfortran, you need to use the -L argument to tell it in which directory  
to find the library or DLL and the -l argument to tell gfortran what library to 
use in that directory.  So if you installed the libraries netcdf in 
/usr/local/lib, then you would use gfortran options such as

  gfortran -I/usr/local/include simple_xy_wr.f -L/usr/local/lib -lnetcdf

The gfortran compiler you're using is looking for Fortran routine names with a 
single appended underscore.  I'm not sure which DLL you're using, but the two 
we have available use different conventions for constructing names in the 
Fortran interface, so if you're invoking gfortran with the right arguments, you 
might try the other one.  The ones I know a little about are:
  ftp://ftp.unidata.ucar.edu/pub/netcdf/contrib/win32/win32_ifort_dll.tar.gz

and

ftp://ftp.unidata.ucar.edu/pub/netcdf/contrib/win32/win32_pgi_dll.tar.gz

but I'm not sure which one uses appended single underscores.  I'm CC:ing Ed who 
can tell you if this is right.

Your other concern was about using the F77 interface from F90.  That should not 
be a problem, since F90 programs can call F77 libraries and an F77 program is 
also an F90 program.  In fact, the F90 netCDF interface is implemented by 
calling above the F77 netCDF interface currently, so compatibility is assured.
