 /***** Select the tagging scheme.  *****/
 /* There are basically two options that control the tagging scheme:
-   - NO_UNION_TYPE says that Lisp_Object should be an integer instead
-     of a union.
+   - USE_LISP_UNION_TYPE says that Lisp_Object should be a union instead
+     of an integer.
    - USE_LSB_TAG means that we can assume the least 3 bits of pointers are
      always 0, and we can thus use them to hold tag bits, without
      restricting our addressing space.
