+
+ * coding.c (encode_coding_raw_text): Avoid unnecessary test
+ the first time through the loop, since we know p0 < p1 then.
+ This also avoids a gcc -Wstrict-overflow warning.
+
+ * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
+ leading to a memory leak, possible in functions like
+ load_charset_map_from_file that can allocate an unbounded number
+ of objects (Bug#8318).
+
+ * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
+ that could (at least in theory) be that large.
+
+ * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
+ This is less likely to overflow, and avoids undefined behavior if
+ overflow does occur. All callers changed. Use strtoul to scan
+ for the unsigned long integer.
+ (pint2hrstr): Simplify and tune code slightly.
+ This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
+
+ * scroll.c (do_scrolling): Work around GCC bug 48228.
+ See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
+
+ * frame.c (Fmodify_frame_parameters): Simplify loop counter.
+ This also avoids a warning with gcc -Wstrict-overflow.
+ (validate_x_resource_name): Simplify count usage.
+ This also avoids a warning with gcc -Wstrict-overflow.
+
+ * fileio.c (Fcopy_file): Report error if fchown or fchmod
+ fail (Bug#8306).
+
+ * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
+
+ * process.c (Fmake_network_process): Use socklen_t, not int,
+ where POSIX says socklen_t is required in portable programs.
+ This fixes a porting bug on hosts like 64-bit HP-UX, where
+ socklen_t is wider than int (Bug#8277).
+ (Fmake_network_process, server_accept_connection):
+ (wait_reading_process_output, read_process_output):
+ Likewise.
+
+ * process.c: Rename or move locals to avoid shadowing.
+ (list_processes_1, Fmake_network_process):
+ (read_process_output_error_handler, exec_sentinel_error_handler):
+ Rename or move locals.
+ (Fmake_network_process): Define label "retry_connect" only if needed.
+ (Fnetwork_interface_info): Fix pointer signedness.
+ (process_send_signal): Add cast to avoid pointer signedness problem.
+ (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
+ (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
+
+ Make tparam.h and terminfo.c consistent.
+ * cm.c (tputs, tgoto, BC, UP): Remove extern decls. Include
+ tparam.h instead, since it declares them.
+ * cm.h (PC): Remove extern decl; tparam.h now does this.
+ * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
+ * terminfo.c: Include tparam.h, to check interfaces.
+ (tparm): Make 1st arg a const pointer in decl. Put it at top level.
+ (tparam): Adjust signature to match interface in tparam.h;
+ this removes some undefined behavior. Check that outstring and len
+ are zero, which they always are with Emacs.
+ * tparam.h (PC, BC, UP): New extern decls.
+
+ * xftfont.c (xftfont_shape): Now static, and defined only if needed.
+ (xftfont_open): Rename locals to avoid shadowing.
+
+ * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
+ (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
+ (OTF_TAG_SYM): Omit macro if not needed.
+ (ftfont_list): Remove unused local.
+ (get_adstyle_property, ftfont_pattern_entity):
+ (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
+ Rename locals to avoid shadowing.
+
+ * xfont.c (xfont_list_family): Mark var as initialized.
+
+ * xml.c (make_dom): Now static.
+
+ * composite.c (composition_compute_stop_pos): Rename local to
+ avoid shadowing.
+ (composition_reseat_it): Remove unused locals.
+ (find_automatic_composition, composition_adjust_point): Likewise.
+ (composition_update_it): Mark var as initialized.
+ (find_automatic_composition): Mark vars as initialized,
+ with a FIXME (Bug#8290).
+
+ character.h: Rename locals to avoid shadowing.
+ * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
+ (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
+ (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
+ (BUF_DEC_POS): Be more systematic about renaming local temporaries
+ to avoid shadowing.
+
+ * textprop.c (property_change_between_p): Remove; unused.
+
+ * intervals.c (interval_start_pos): Now static.
+
+ * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
+
+ * atimer.c (start_atimer, append_atimer_lists, set_alarm): Rename
+ locals to avoid shadowing.
+
+ * sound.c (wav_play, au_play, Fplay_sound_internal):
+ Fix pointer signedness.
+ (alsa_choose_format): Remove unused local var.
+ (wav_play): Initialize a variable to 0, to prevent undefined
+ behavior (Bug#8278).
+
+ * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
+
+ * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
+
+ * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
+ clobbering (Bug#8298).
+ * sysdep.c (sys_subshell): Likewise.
+ Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
+
+ * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
+ This should get cleaned up, so that child_setup has the
+ same signature on all platforms.
+
+ * callproc.c (call_process_cleanup): Now static.
+ (relocate_fd): Rename locals to avoid shadowing.

* xterm.c (x_clear_frame): Remove XClearWindow call. This appears
