+
+        Use 0 for Qnil
+        Fixes Bug#15880.
+        If USE_LSB_TAG, arrange for the representation of Qnil to be zero so
+        that NILP (x) is equivalent to testing whether x is 0 at the
+        machine level.  The overall effects of this and the previous patch
+        shrink the size of the text segment by 2.3% and speeds up
+        compilation of all the .elc files by about 0.5% on my platform,
+        which is Fedora 20 x86-64.
+        * lisp.h (lisp_h_XPNTR, lisp_h_XSYMBOL, lisp_h_XUNTAG)
+        (make_lisp_symbol) [USE_LSB_TAG]:
+        Symbols now tag the difference from lispsym, not the pointer.
+        (lisp_h_XUNTAGBASE, TAG_SYMPTR): New macros.
+        (Lisp_Int0, Lisp_Int1, Lisp_Symbol, Lisp_Misc, Lisp_String, Lisp_Cons):
+        Renumber so that Lisp_Symbol is 0, so that Qnil is zero.
+        (XSYMBOL): New forward decl.
+        (XUNTAGBASE): New function.
+        (XUNTAG): Use it.
+
+        Compute C decls for DEFSYMs automatically
+        Fixes Bug#15880.
+        This patch also makes Q constants (e.g., Qnil) constant addresses
+        from the C point of view.

+        Use XSYMBOL_INIT (Qfoo) and struct Lisp_Symbol * rather than &Qfoo and
+        Lisp_Object *, since Qfoo is no longer an object whose address can be
+        taken.  All uses changed.
+        * eval.c (run_hook): New function.  Most uses of Frun_hooks changed to
+        use it, so that they no longer need to take the address of a Lisp sym.
+        (syms_of_eval): Don't use DEFSYM on Vrun_hooks, as it's a variable.
+        * frame.c (syms_of_frame): Add defsyms for the frame_parms table.

+        * keymap.c (syms_of_keymap): Use DEFSYM for Qmenu_bar and Qmode_line

+        (enum symbol_interned, enum symbol_redirect, struct Lisp_Symbol)
+        (EXFUN, DEFUN_ARGS_MANY, DEFUN_ARGS_UNEVALLED, DEFUN_ARGS_*):

+        'temacs -nw' should not call missing functions
+        Without this patch, "temacs -nw" fails with the diagnostic
+        "emacs: Symbol's function definition is void: frame-windows-min-size"
+        and messes up the tty's state.

+
+        batch write-region no longer says "Wrote FOO"
