The casts from pointer to unsigned int caused warnings because of the
type size difference. I tried replacing the %x placeholders with %p,
but then GCC gave different warnings: "warning: ISO C forbids
conversion of function pointer to object pointer type". Instead of
fighting with the casts, I just removed the pointer printing
altogether, since that didn't seem very interesting information.
