(get_utf8_string, xg_store_widget_in_map):
Check for size-calculation overflow.
(get_utf8_string): Use ptrdiff_t, not size_t, where either will
do, as we prefer signed integers.
(id_to_widget.max_size, id_to_widget.used)
(xg_store_widget_in_map, xg_remove_widget_from_map)
(xg_get_widget_from_map, xg_get_scroll_id_for_window)
(xg_remove_scroll_bar, xg_update_scrollbar_pos):
Use and return ptrdiff_t, not int.
(xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
* gtkutil.h: Change prototypes to match the above.
(set_menu_bar_lines, x_set_frame_parameters, x_set_scroll_bar_width)
(x_figure_window_size): Check for integer overflow.
(x_set_alpha): Do not assume XINT fits in int.
(set_time_zone_rule): Don't assume environment length fits in int.
(message_length): Now ptrdiff_t, not int.
(Fmessage_box): Don't update size until allocation succeeds.
Don't assume message length fits in int.
(Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
(get_doc_string_buffer_size): Now ptrdiff_t, not int.
(get_doc_string): Check for size calculation overflow.
Don't update size until allocation succeeds.
(get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
EMACS_INT, where ptrdiff_t will do.
(Fsubstitute_command_keys): Check for string overflow.
(Fccl_execute_on_string): Check for memory overflow.
Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
Redo buffer-overflow calculations to avoid integer overflow.
(overlays_at, overlays_in, record_overlay_string, overlay_strings):
Don't update size of array until after memory allocation succeeds,
because xmalloc/xrealloc may not return.
(bidi_shelve_header_size): New constant.
(bidi_cache_ensure_space, bidi_shelve_cache): Use it.
(bidi_cache_ensure_space): Avoid integer overflow when allocating.

and the surrounding thread.
* minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
rather than fgets, and retry after EINTR. Otherwise, 'emacs
--batch -f byte-compile-file' fails on OpenBSD if an inactivity
timer goes off.
* s/openbsd.h (BROKEN_SIGIO): Define.
* unexelf.c (unexec) [__OpenBSD__]:
Don't update the .mdebug section of the Alpha COFF symbol table.
* character.c (Fchar_width, c_string_width, lisp_string_width):
* character.h (CHAR_WIDTH):
* indent.c (MULTIBYTE_BYTES_WIDTH):
Use sanitize_char_width to avoid undefined and/or bad behavior
with outlandish widths.
* character.h (sanitize_tab_width): Renamed from sanitize_width,
now that we have two such functions. All uses changed.
(sanitize_char_width): New inline function.
* character.h (sanitize_width): New inline function.
(SANE_TAB_WIDTH): New macro.
(ASCII_CHAR_WIDTH): Use it.
* indent.c (sane_tab_width): Remove. All uses replaced by
SANE_TAB_WIDTH (current_buffer).
* xdisp.c (init_iterator): Use SANE_TAB_WIDTH.
If fchown fails to set both uid and gid, try to set just gid,
as that is sometimes allowed. Adjust the file's mode to eliminate
setuid or setgid bits that are inappropriate if fchown fails.
to compare Lisp_Objects.
* src/gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
global_gnutls_log_level, don't mistake it for a Lisp_Object.
(init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
(scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
(x_send_scroll_bar_event): Likewise. Check that the size does not
exceed limits imposed by XClientMessageEvent, as well as the usual
ptrdiff_t and size_t limits.
* mh-folder.el (mh-inc-folder, mh-modify, mh-scan-folder)
(mh-make-folder): Revert to switch-to-buffer, as the Emacs folks
decided that it was fine to use it in programs.
