The main advantage of N64 binaries is 64-bit pointers (i.e. arrays
bigger than 2GB). It also lets C program access files > 2GB without
resorting to the "long long" type, but I don't think that is an issue
for CNS. All else being equal, N32 binaries will run just as fast or
faster than N64 binaries.
N32 allows a single binary to run across the entire SGI spectrum. N64
binaries won't run on O2s, Indigos, or Indigo2 R4400s.
