+        * lisp.h (TAG_SYMPTR, XSYMBOL_INIT): Remove, replacing with ...
+        (TAG_SYMOFFSET, SYMBOL_INDEX): ... new macros that deal with
+        symbol indexes rather than pointers, and which work better on MSB
+        hosts because they shift right before tagging.  All uses changed.
+        (DEFINE_LISP_SYMBOL_BEGIN, DEFINE_LISP_SYMBOL_END):

+
+        Port new Lisp symbol init to x86 --with-wide-int
+        * lisp.h (DEFINE_LISP_SYMBOL_BEGIN, DEFINE_LISP_SYMBOL_END):
+        Define to empty on platforms where EMACS_INT_MAX != INTPTR_MAX, as
+        GCC (at least) does not allow a constant initializer to widen an
+        address constant.
+
+        * lisp.h (TAG_SYMPTR): Don't do arithmetic on NULL.
+        This is a followup to the "Port Qnil==0 XUNTAG to clang" patch.
+        Although clang doesn't need it, some other compiler might, and
+        it's easy enough to be safe.
+
+        * conf_post.h (ATTRIBUTE_ALLOC_SIZE): Port to clang 3.5.0.
+        Apparently clang removed support for the alloc_size attribute.
+
+        Port Qnil==0 XUNTAG to clang
+        clang has undefined behavior if the program subtracts an integer
+        from (char *) 0.  Problem reported by YAMAMOTO Mitsuharu in:
+        http://lists.gnu.org/archive/html/emacs-devel/2015-01/msg00132.html
+        * lisp.h (lisp_h_XUNTAG) [USE_LSB_TAG]:

+
+        Port GFileMonitor * hack to Qnil==0 platforms
+        Reported by Glenn Morris in: http://bugs.gnu.org/15880#112
+        * gfilenotify.c (monitor_to_lisp, lisp_to_monitor): New functions.
+        (dir_monitor_callback, Fgfile_add_watch, Fgfile_rm_watch): Use them.
+
+2015-01-06  Jan Djärv  <jan.h.d@swipnet.se>
+
+        * nsterm.m (x_set_window_size): Call updateFrameSize to get real
+        size instead of using widht/height.  The frame may be constrained.
+
+2015-01-05  Paul Eggert  <eggert@cs.ucla.edu>
+
+        * lisp.h (XSYMBOL): Parenthesize id in forward decl.
+        Needed when neither optimizing nor inlining.
+        Also, sort decls alphabetically.
+
+2015-01-05  Eli Zaretskii  <eliz@gnu.org>
+
+        * w32proc.c, w32.h, w32fns.c, w32font.c, w32menu.c, w32notify.c:
+        * w32proc.c, w32select.c, w32term.c, w32uniscribe.c: Remove
+        declarations of Q* variables that represent symbols.
+
+2015-01-05  Paul Eggert  <eggert@cs.ucla.edu>
+
+        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.

+        Remove Q vars that represent symbols (e.g., Qnil, Qt, Qemacs).
+        These names are now defined automatically by make-docfile.

+        (valid_lisp_object_p, purecopy): Use it.

+        since Qt's address is already known now.

+        when testing whether storage is all bits zero.

+        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.
+        * keyboard.c (syms_of_keyboard): Don't DEFSYM Qmenu_bar here.
+        DEFSYM Qdeactivate_mark before the corresponding var.
+        * keymap.c (syms_of_keymap): Use DEFSYM for Qmenu_bar and Qmode_line
