You're correct, the netCDF version 3 Fortran API isn't quite source-code
compatible with the version 2 API. I've modified the values of the
Fortran error-code parameters in the file "netcdf.inc" to reflect their
netCDF version 3 values. This should make the error codes source-level
compatible. The modified codes passes our tests.
This modification will be part of the next release.
Would you please apply the enclosed patch to the file
"fortran/netcdf.inc" in your netCDF distribution and let me know of any
problems.
