Please instead try our alpha release of netCDF 3.4, which has
modifications for the NEC SX-4 included.  It's available from 

   ftp://ftp.unidata.ucar.edu/pub/netcdf/netcdf-3.4a.tar.Z

I've appended a copy of the instructions in the INSTALL file for the
SX-4 system.

We used f90 with no special options to the Fortran compiler, but see the
appended INSTALL excerpt for flags we used for Cray compatibility mode.

You're welcome.  Please let us know if this doesn't work by email to

        There are SX specific hacks in nc_test and ncx.m4 to deal with
        the broken C preprocessor.

    CC="cc -Xa -hfloat2 -hint64"

        Passes libsrc/t_nc.
        Passes nctest.
        Passes nc_test.
        Passes fortran/ftest.
