        * Makefile.in ($(DESTDIR)${archlibdir}): install-sh moved
        to build-aux (Bug#9169).

+
+       Integer and memory overflow issues (Bug#9397).
+
+       * emacsclient.c (xmalloc): Accept size_t, not unsigned int, to
+       avoid potential buffer overflow issues on typical 64-bit hosts.
+       Return void *, not long *.
+       (get_current_dir_name): Report a failure, instead of looping
+       forever, if buffer size calculation overflows.  Treat malloc
+       failures like realloc failures, as that has better behavior and is
+       more consistent.  Do not check whether xmalloc returns NULL, as
+       that's not possible.
+       (message): Do not arbitrarily truncate message to 2048 bytes when
+       sending it to stderr; use vfprintf instead.
+       (get_server_config, set_local_socket)
+       (start_daemon_and_retry_set_socket): Do not alloca
+       arbitrarily-large buffers; that's not safe.
+       (get_server_config, set_local_socket): Do not use sprintf when its
+       result might not fit in 'int'.
+       (set_local_socket): Do not assume uid fits in 'int'.
+
+       * etags.c (xmalloc, xrealloc): Accept size_t, not unsigned int,
+       to avoid potential buffer overflow issues on typical 64-bit hosts.
+       (whatlen_max): New static var.
+       (main): Avoid buffer overflow if subsidiary command length is
+       greater than BUFSIZ or 2*BUFSIZ + 20. Do not use sprintf when its
+       result might not fit in 'int'.
+
+       * movemail.c (main): Do not use sprintf when its result might not fit
+       in 'int'.  Instead, put the possibly-long file name into the
+       output of pfatal_with_name.
+
+       * update-game-score.c: Include <limits.h>
+       (get_user_id): Do not assume uid fits in 'int'.  Simplify.

        Assume freestanding C89 headers, string.h, stdlib.h.
