Casting an integer to a void * generates a "cast to pointer from integer
of different size" warning. Cast the integer to an unsigned long first
to fix it.

I've kept this change separate from 1/3 to show why 1/3 and 2/3 are required
to fix a compilation warning before applying 3/3. Feel free to squash 1/3 and
2/3 if preferred.
