+2012-07-12  Paul Eggert  <eggert@cs.ucla.edu>
+
+        * movemail.c: Add missing 'defined'.
+        Suggested by Sven Joachim in
+        <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00218.html>.
+
+2012-07-11  Paul Eggert  <eggert@cs.ucla.edu>
+
+        Port 'movemail' again to Solaris and similar hosts.
+        See Susan Cragin's report in
+        <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00199.html>.
+        * movemail.c (xmalloc): Also define if !DISABLE_DIRECT_ACCESS &&
+        !MAIL_USE_MMDF && !MAIL_USE_SYSTEM_LOCK.  Move up, so it doesn't
+        need a forward declaration.
+        (main): Rewrite to avoid no-longer-present function 'concat', if
+        !DISABLE_DIRECT_ACCESS && !MAIL_USE_MMDF && !MAIL_USE_SYSTEM_LOCK.
+
+        Assume strerror.
+        * emacsclient.c, movemail.c, update-game-score.c (strerror)
+        [!HAVE_STRERROR]: Remove.
+
+2012-07-10  Paul Eggert  <eggert@cs.ucla.edu>
+
+        EMACS_TIME simplification (Bug#11875).
+        * profile.c (TV2): Remove no-longer-needed static var.
+
+        Simplify by avoiding confusing use of strncpy etc.
+        * etags.c (write_classname, C_entries):
+        Use sprintf rather than strncpy or strncat.
+        * etags.c (consider_token, C_entries, HTML_labels, Prolog_functions)
+        (Erlang_functions, substitute, readline_internal, savenstr):
+        * movemail.c (mail_spool_name):
+        Use memcpy rather than strncpy or strncat when either will do.
+        * make-docfile.c (write_c_args):
+        Use memcmp rather than strncmp when either will do.
+        * movemail.c (pop_retr):
+        * pop.c (pop_stat, pop_list, pop_multi_first, pop_last)
+        (socket_connection, pop_getline, sendline, getok):
+        Use snprintf rather than strncpy or strncat.
+        * movemail.c (concat): Remove; no longer needed.
+        (xmalloc): Define only if needed, now that concat has gone away.
+        Return void *.  All uses changed.
+
+2012-07-09  Paul Eggert  <eggert@cs.ucla.edu>
+
+        Add GCC-style 'const' attribute to functions that can use it.
+        * etags.c (number_len): Add ATTRIBUTE_CONST.
+
