Wes,

I'm glad you were able to write the file you wanted, but you should be aware 
that the changes you made to the library make it possible to write "netCDF" 
files that cannot be read successfully on some other platforms.  

The reason only the last variable can be arbitrarily large and other variables 
are limited in size to either 4 GiB (without unlimited dimension) or only 4 
GiB/record (with unlimited dimension) is to make sure 32-bit systems can access 
the data, even if it's written on a 64-bit system.  Maybe that's not a problem 
for you if you know the data will only be read with the modified library on 
64-bit platforms.
