105 - USE_LISP_UNION_TYPE says that Lisp_Object should be a union instead
107 - USE_LSB_TAG means that we can assume the least 3 bits of pointers are
108 always 0, and we can thus use them to hold tag bits, without
109 restricting our addressing space.
111 If USE_LSB_TAG is not set, then we use the top 3 bits for tagging, thus
112 restricting our possible address range. Currently USE_LSB_TAG is not
113 allowed together with a union. This is not due to any fundamental
114 technical (or political ;-) problem: nobody wrote the code to do it yet.
116 USE_LSB_TAG not only requires the least 3 bits of pointers returned by
117 malloc to be 0 but also needs to be able to impose a mult-of-8 alignment
118 on the few static Lisp_Objects used: all the defsubr as well

1317 binding is loaded it is necessary to find which binding goes with
1318 the current buffer and selected frame, then load it. To load it,

1780 `fnname' should be the name of the function in C.
1781 By convention, it starts with F.
1782 `sname' should be the name for the C constant structure
1783 that records information on this function for internal use.
1784 By convention, it should be the same as `fnname' but with S instead of F.
1785 It's too bad that C macros can't compute this from `fnname'.
1786 `minargs' should be a number, the minimum number of arguments allowed.
1787 `maxargs' should be a number, the maximum number of arguments allowed,
1788 or else MANY or UNEVALLED.
1789 MANY means pass a vector of evaluated arguments,
1790 in the form of an integer number-of-arguments
1791 followed by the address of a vector of Lisp_Objects
1792 which contains the argument values.
1793 UNEVALLED means pass the list of unevaluated arguments
1794 `intspec' says how interactive arguments are to be fetched.
1795 If the string starts with a `(', `intspec' is evaluated and the resulting
1796 list is the list of arguments.
1797 If it's a string that doesn't start with `(', the value should follow
1798 the one of the doc string for `interactive'.
1799 A null string means call interactively with no arguments.
1800 `doc' is documentation for the user. */
