+        Timestamp fixes for undo (Bug#14824).
+        * atimer.c (schedule_atimer):
+        * fileio.c (Ffile_newer_than_file_p):
+        Minor cleanup: use EMACS_TIME_LT so that we can remove EMACS_TIME_GT.
+        * buffer.c (buffer-undo-list): Document (t . 0) and (t . -1).
+        * fileio.c (Fclear_visited_file_modtime): Move to lisp/files.el.
+        (syms_of_fileio): Remove Sclear_visited_file_name.
+        (Fvisited_file_modtime): Return -1, not (-1 ...), when the visited
+        file doesn't exist; this avoids an ambiguity with negative timestamps.
+        (Fset_visited_file_modtime): Accept -1 and 0 as time-list arg.
+        * systime.h (make_emacs_time, invalid_emacs_time):
+        Don't assume struct timespec layout; POSIX doesn't guarantee it.
+        (EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE): Remove.
+        * undo.c (record_first_change): Push (visited-file-modtime) onto
+        undo list rather than reimplementing it by hand, incorrectly.
