Should use the GINT_TO_POINTER() and GPOINTER_TO_INT() macros to do
this portably; apparently on some machines you need:

 (gpointer) (glong) my_int       - for conversion to pointer
 (gint) (glong) my_int           - for conversion from pointer

This comes up when sizeof(void*) is larger than sizeof(int) but equal
to sizeof(long).  GINT_TO_POINTER and GPOINTER_TO_INT do the right
thing for the machine.
