104 - USE_LISP_UNION_TYPE says that Lisp_Object should be a union instead

107 always 0, and we can thus use them to hold tag bits, without
108 restricting our addressing space.
110 If USE_LSB_TAG is not set, then we use the top 3 bits for tagging, thus
111 restricting our possible address range. Currently USE_LSB_TAG is not
112 allowed together with a union. This is not due to any fundamental
113 technical (or political ;-) problem: nobody wrote the code to do it yet.
115 USE_LSB_TAG not only requires the least 3 bits of pointers returned by
116 malloc to be 0 but also needs to be able to impose a mult-of-8 alignment
