Exactly. You are printing an unsigned long int value
using a signed integer format.

You should use the right format. In this case you can
use "%lu" in stead of "%d", which is specific to
unsigned long integers.
You can have a look at the printf documentation for a
complete list of all available formats (type "info libc
alpha printf" in a dos box)
