So, in sum, you would like to use "%lu" and no cast to print size_t
values? I guess that should give correct results, as long as
sizeof(size_t) == sizeof(unsigned long) on all our supported platforms
(although that's certainly not a generally safe assumption, and
definitely not as safe as the sizeof(size_t) <= sizeof(unsigned long)
assumption that I was making).
