111 always 0, and we can thus use them to hold tag bits, without
112 restricting our addressing space.

115 restricting our possible address range. Currently USE_LSB_TAG is not
116 allowed together with a union. This is not due to any fundamental
117 technical (or political ;-) problem: nobody wrote the code to do it yet.
119 USE_LSB_TAG not only requires the least 3 bits of pointers returned by
120 malloc to be 0 but also needs to be able to impose a mult-of-8 alignment

1791 It's too bad that C macros can't compute this from `fnname'.
1792 `minargs' should be a number, the minimum number of arguments allowed.
1793 `maxargs' should be a number, the maximum number of arguments allowed,
1794 or else MANY or UNEVALLED.
1795 MANY means pass a vector of evaluated arguments,
1796 in the form of an integer number-of-arguments
1797 followed by the address of a vector of Lisp_Objects
1798 which contains the argument values.
1799 UNEVALLED means pass the list of unevaluated arguments
1800 `intspec' says how interactive arguments are to be fetched.
1801 If the string starts with a `(', `intspec' is evaluated and the resulting
1802 list is the list of arguments.
1803 If it's a string that doesn't start with `(', the value should follow
1804 the one of the doc string for `interactive'.
1805 A null string means call interactively with no arguments.
1806 `doc' is documentation for the user. */
