The include files such as netcdf.h would be the same, but one is built
on a 64-bit IRIX64 platform, while the other was built on a 32-bit IRIX
platform.  I think they were both built with the "-n32" compiler flag
though, which means there is no important difference.  If you start
needing to deal with files larger than 2 Gbytes, I don't think either
of these would work, because they weren't compiled for Large File
Support.
