- * used to perform integer-only operations on pointers. This failed on
- * VMS with 64-bit pointers (CC /POINTER_SIZE = 64) because size_t is
- * still only 32 bits. What's needed in these cases is an integer type
- * with the same size as a pointer, which size_t is not certain to be.
- * The only fix here is VMS-specific.
