USE_LSB_TAG now is always defined to be either 0 or 1. All uses changed. (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the code works fine either way, and efficiency is not a concern here, as the union type is for debugging, not for production. (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]: Use an inline function on all platforms when using the union type, since this is simpler and 'static inline' can be used portably within Emacs now. (LISP_INITIALLY_ZERO): New macro. (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove. (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.
