Man, I knew ARM sucked, but I didn't know it was this bad :-)
I was going to suggestion replacing the division operations with calls to
lldiv(), but we're actually doing a 64-by-64 bit division here:
n = size / d;
which means that in order to support support printing 64-bit numbers on ARM,
we might need to completely rewrite print_size() to avoid division on 64-bit
numbers.
Wolfgang, do you have any suggestions?
