This came up for me because I'm on x86_64 which has 64-bit pointers. Hence the
difference between two pointers (ptrdiff_t) can be 64-bit, so %d would be too
small for printing these. %td is for ptrdiff_t (it instructs printf to parse
the correct size for any architecture). Perhaps it's a GNU extension; I'm not
sure (I just found it in the man page on my GNU/Linux box).
