Thanks for pointing this out and providing a fix. I would have had a hard time figuring that one out! I have checked your fix into the repository and it is in the current snapshot release: ftp://ftp.unidata.ucar.edu/pub/netcdf/netcdf-4-daily.tar.gz Please give it a try and let me know if it works for you.
