+**| and is also the same as another macro appearing in stdlib.h.
+**| We want these offsets so we can correctly convert pointers
+**| to member slots back into pointers to enclosing objects, and
+**| have this exactly match what the compiler thinks is true.
+**|
+**|| Basically we are asking the compiler to determine the offset at
+**| compile time, and we use the definition of address artithmetic
+**| to do this.  By casting integer zero to a pointer of type obj*,
+**| we can reference the address of a slot in such an object that
+**| is hypothetically physically placed at address zero, but without
+**| actually dereferencing a memory location.  The absolute address
+**| of slot is the same as offset of that slot, when the object is
+**| placed at address zero.
