103 - USE_LISP_UNION_TYPE says that Lisp_Object should be a union instead

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