Where the value printed is an offset (whose range will always fit) the cast uses a 32-bit type, otherwise, where it is a host memory address, the `long' type is used and the width of the number printed adjusted according to the size of this type. Tested with both 32-bit and 64-bit compilation, as well as at the run time (with the debug messages affected enabled). Signed-off-by: Maciej W.
