+
+        Fix a race with verify-visited-file-modtime (Bug#12863).
+        Since at least 1991 Emacs has ignored an mtime difference of no
+        more than one second, but my guess is that this was to work around
+        file system bugs that were fixed long ago.  Since the race is
+        causing problems now, let's remove that code.
+        * fileio.c (Fverify_visited_file_modtime): Do not accept a file
+        whose time stamp is off by no more than a second.  Insist that the
+        file time stamps match exactly.
+
+2012-11-12  Dmitry Antipov  <dmantipov@yandex.ru>
+
+        * frame.h (struct frame): Convert external_tool_bar member to
+        1-bit unsigned bitfield.
+        * termhooks.h (struct terminal): Remove mouse_moved member since
+        all users are long dead.  Adjust comment on mouse_position_hook.
+
+2012-11-12  Dmitry Antipov  <dmantipov@yandex.ru>
+
+        Simplify by using FOR_EACH_FRAME here and there.
+        * frame.c (next_frame, prev_frame, other_visible_frames)
+        (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
+        * w32term.c (x_window_to_scroll_bar): Likewise.
+        * window.c (window_list): Likewise.
+        * xdisp.c (x_consider_frame_title): Likewise.

+
+2012-11-12  Paul Eggert  <eggert@cs.ucla.edu>
+
+        * data.c (Qdefalias_fset_function): Now static.
+
+        Another tweak to vectorlike_header change.
+        * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
+        Remove, and replace all uses with ...
+        (next_in_free_list, set_next_in_free_list):
+        New functions, which respect C's aliasing rules better.
+
+2012-11-11  Paul Eggert  <eggert@cs.ucla.edu>
+
+        * window.c (list4i): Rename from 'quad'.  All uses changed.
+        Needed because <sys/types.h> defines 'quad' on Solaris 10.
+
+2012-11-11  Juanma Barranquero  <lekktu@gmail.com>
+
+        * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence

+
+2012-11-10  Eli Zaretskii  <eliz@gnu.org>
+
+        * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
+        amount when the scroll margins are too large.  When scrolling
+        backwards in the buffer, give up if cannot reach point or the
+        scroll margin within a reasonable number of screen lines.  Fixes
+        point position in window under scroll-up/down-aggressively when
+        point is positioned many lines beyond the window top/bottom.
+        (Bug#12811)
+
+        * ralloc.c (relinquish): If real_morecore fails to return memory
+        to the system, don't crash; instead, leave the last heap
+        unchanged and return.  (Bug#12774)
+
+2012-11-09  Stefan Monnier  <monnier@iro.umontreal.ca>

+        * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
+        vectorlike object on the free list.  This is introduced to avoid

+        of the old SXHASH_COMBINE.
+        * profiler.c (hashfn_profiler): Use it, instead of having a

+
+2012-11-08  Stefan Monnier  <monnier@iro.umontreal.ca>
+
