+
+        * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
+
+        Use functions, not macros, for up- and down-casing (Bug#8254).
+        * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
+        (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove.  All callers changed
+        to use the following functions instead of these macros.
+        (downcase): Adjust to lack of DOWNCASE_TABLE.  Return int, not
+        EMACS_INT, since callers assume the returned value fits in int.
+        (upcase1): Likewise, for UPCASE_TABLE.
+        (uppercasep, lowercasep, upcase): New static inline functions.
+        * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

+        Remove unused local vars.

+        which gcc can warn about.
+        (regex_compile, re_match_2_internal): Mark locals as initialized.
+        (RETALLOC_IF): Define only if needed.
+        (WORDCHAR_P): Likewise.  This one is never needed, but is used
+        only in a comment talking about a compiler bug, so put inside
+        the #if 0 of that comment.
+        (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
+        (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

+
+        * character.h (INC_POS, DEC_POS): Rename locals to avoid shadowing.
+
+        * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
+        All uses changed.
+        (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
+        Rename locals to avoid shadowing.
+        (Fvertical_motion): Mark locals as initialized.
+
+        * casefiddle.c (casify_object, casify_region): Now static.
+        (casify_region): Mark local as initialized.
+
+        * cmds.c (internal_self_insert): Rename local to avoid shadowing.
+
+        * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
+        New macros, so that the caller can use some names other than
+        gcpro1, gcpro2, etc.
+        (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
+        of the new macros.
+        (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
+        argument, for consistency with GCPRO2_VAR, etc: it is now the
+        prefix of the variable, not the variable itself.  All uses
+        changed.
+        * dired.c (directory_files_internal, file_name_completion):
+        Rename locals to avoid shadowing.
+
+        Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
+        An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
+        dired.c's scmp function, had undefined behavior.
+        * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
+        (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
+        * buffer.h: ... to here, because these macros use current_buffer,
+        and the new implementation with inline functions needs to have
+        current_buffer in scope now, rather than later when the macros
+        are used.
+        (downcase, upcase1): New static inline functions.
+        (DOWNCASE, UPCASE1): Reimplement using these functions.
+        This avoids undefined behavior in expressions like
+        DOWNCASE (x) == DOWNCASE (y), which previously suffered
+        from race conditions in accessing the global variables
+        case_temp1 and case_temp2.
+        * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
+        * lisp.h (case_temp1, case_temp2): Remove their decls.
+        * character.h (ASCII_CHAR_P): Move from here ...
+        * lisp.h: ... to here, so that the inline functions mentioned
+        above can use them.
+
+        * dired.c (directory_files_internal_unwind): Now static.
+
+        * fileio.c (file_name_as_directory, directory_file_name):
+        (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
+        Now static.
+        (file_name_as_directory): Use const pointers when appropriate.
+        (Fexpand_file_name): Likewise.  In particular, newdir might
+        point at constant storage, so make it a const pointer.
+        (Fmake_directory_internal, Fread_file_name): Remove unused vars.
+        (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
+        signedness issues.
+        (Fset_file_times, Finsert_file_contents, auto_save_error):
+        Rename locals to avoid shadowing.
+
+        * minibuf.c (choose_minibuf_frame_1): Now static.
+        (Ftry_completion, Fall_completions): Rename or remove locals
+        to avoid shadowing.
+
+        * marker.c (bytepos_to_charpos): Remove; unused.
+
+        * lisp.h (verify_bytepos, count_markers): New decls,
+        so that gcc does not warn that these functions aren't declared.
+
+        * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
+        (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
+        (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
+        (copy_text): Remove unused local var.
+
+        * filelock.c (within_one_second): Now static.
+        (lock_file_1): Rename local to avoid shadowing.
+
+        * buffer.c (fix_overlays_before): Mark locals as initialized.
+        (fix_start_end_in_overlays): Likewise.  This function should be
+        simplified by using pointers-to-pointers, but that's a different
+        matter.
+        (switch_to_buffer_1): Now static.
+        (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
+        (report_overlay_modification): Rename locals to avoid shadowing.
+
+        * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
+        Fix pointer signedness issue.
+        (sys_subshell): Mark local as volatile if checking for lint,
+        to suppress a gcc -Wclobbered warning that does not seem to be right.
+        (MAXPATHLEN): Define only if needed.
+
+        * process.c (serial_open, serial_configure): Move decls from here ...
+        * systty.h: ... to here, so that they can be checked.
+
+        * fns.c (get_random, seed_random): Move extern decls from here ...
+        * lisp.h: ... to here, so that they can be checked.
+
+        * sysdep.c (reset_io): Now static.
+        (wait_for_termination_signal): Remove; unused.
+
+        * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
+        (copy_keymap_item, append_key, push_text_char_description):
+        Now static.
+        (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
+        (DENSE_TABLE_SIZE): Remove; unused.
+        (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
+        (describe_map_tree):
+        Rename locals to avoid shadowing.
+
+        * keyboard.c: Declare functions static if they are not used elsewhere.
+        (echo_char, echo_dash, cmd_error, top_level_2):
+        (poll_for_input, handle_async_input): Now static.
+        (read_char, kbd_buffer_get_event, make_lispy_position):
+        (make_lispy_event, make_lispy_movement, apply_modifiers):
+        (decode_keyboard_code, tty_read_avail_input, menu_bar_items):
+        (parse_tool_bar_item, read_key_sequence, Fread_key_sequence):
+        (Fread_key_sequence_vector): Rename locals to avoid shadowing.
+        (read_key_sequence, read_char): Mark locals as initialized.
+        (Fexit_recursive_edit, Fabort_recursive_edit): Mark with NO_RETURN.
+
+        * keyboard.h (make_ctrl_char): New decl.
+        (mark_kboards): Move decl here ...
+        * alloc.c (mark_kboards): ... from here.
+
+        * lisp.h (force_auto_save_soon): New decl.
+
+        * emacs.c (init_cmdargs): Rename local to avoid shadowing.
+        (DEFINE_DUMMY_FUNCTION): New macro.
+        (__do_global_ctors, __do_global_ctors_aux, __do_global_dtors, __main):
+        Use it.
+        (main): Add casts to avoid warnings
+        if GCC considers string literals to be constants.
+
+        * lisp.h (fatal_error_signal): Add decl, since it's exported.
+
+        * dbusbind.c: Pointer signedness fixes.
+        (xd_signature, xd_append_arg, xd_initialize):
+        (Fdbus_call_method, Fdbus_call_method_asynchronously):
+        (Fdbus_method_return_internal, Fdbus_method_error_internal):
+        (Fdbus_send_signal, xd_read_message_1, Fdbus_register_service):
+        (Fdbus_register_signal): Use SSDATA when the context wants char *.
+
+        * dbusbind.c (Fdbus_init_bus): Add cast to avoid warning
+        if GCC considers string literals to be constants.
+        (Fdbus_register_service, Fdbus_register_method): Remove unused vars.
+
