* emacs-lisp/debug.el (debug): When debugger-will-be-back is
non-nil, restore window configuration (Bug#12623).

* doc/emacs/files.texi (File Conveniences): ImageMagick enabled by default.

* doc/lispref/display.texi (ImageMagick Images): ImageMagick enabled by default.

* fileio.c (Fwrite_region): Avoid race condition if a file is
removed or renamed by some other process immediately after Emacs
writes it but before Emacs stats it.  Do not assume that stat (or
fstat) succeeds.
* image.c (slurp_file): Resolve the file name with fopen + fstat
rather than stat + fopen.
(pbm_read_file) [0]: Remove unused code with stat race.
* process.c (allocate_pty) [HAVE_PTYS && !PTY_ITERATION && !PTY_OPEN]:
Remove ineffective code with stat race.

* lisp/help-fns.el (describe-variable, describe-function-1):
* lisp/help-mode.el (help-make-xrefs): Remove error handler, made unneeded.

(EV_TRAILER, sendScrollEventAtLoc:fromEvent:): Call hold_event if
! q_event_ptr.
(hold_event): New function.

return.
(setPosition:portion:whole:): Send SIGIO to ourselves if apploopnr
is zero (Bug#12384).

 src/makefile.w32-in ($(BLD)/fileio.$(O)): Add sys/file.h.

 src/fileio.c (check_existing): New function.
 (make_temp_name, Ffile_exists_p, Ffile_writable_p): Call it
 instead of calling 'stat', when what's needed is to check whether
 a file exists.  This avoids expensive system calls on MS-Windows.
 src/w32.c (init_environment): Call 'check_existing' instead of 'stat'.
 src/lread.c (openp) [WINDOWSNT]: Call 'access' instead of 'stat' to
 determine whether a file exists and is not a directory.
 src/lisp.h (check_existing): Add prototype.

* lisp/mail/rmailsum.el (rmail-header-summary):
Fix 2010-11-26 test for multiline Subject: field.

subtitute-key-definition with proper command remapping.
(python-nav--up-list): Fix behavior for blocks on the same level.

* lisp/emacs-lisp/cl-macs.el (cl--defsubst-expand): Idem.

* lisp/emacs-lisp/cl-lib.el (cl--defsubst-expand): Move autoload...
* lisp/emacs-lisp/cl-macs.el (cl--defsubst-expand): ...here.

* lisp/emacs-lisp/bytecomp.el (byte-compile-eval): Adjust to long-ago
changes to the format of load-history.
* src/eval.c (Fautoload): Remember previous autoload status in load-history.

completion-ignore-case in case that var is buffer-local.

Fixes: debbugs:12615

(ns_menu_show):
* xmenu.c (set_frame_menubar, create_and_show_popup_menu)
(xmenu_show, xdialog_show):
Use bool for booleans.
* lread.c (safe_to_load_version): Rename from safe_to_load_p,
as it's not a predicate.  All uses changed.  Omit unnecessary
buffer termination.

(save_excursion_restore): Do not restore mark if it was not saved.

instead of having a wrong decl.

* dispnew.c (sit_for): Distinguish between 3-way display_option
and boolean do_display.

* search.c (scan_buffer, scan_newline):
Use bool for boolean.
* keyboard.c (timers_run, swallow_events)
(detect_input_pending_run_timers):
* process.c (wait_reading_process_output):
Use unsigned for counter where wraparound-on-overflow is desired,
since unsigned is guaranteed to have that behavior and signed is not.
(read_char): Use ptrdiff_t for string length.
(get_input_pending): Remove first argument, since it was always
the same pointer-to-int (now pointer-to-boolean) &input_pending,
and behave as if it had that value.  Return new value of
input_pending.  All callers changed.
* keyboard.h (struct kboard): Use unsigned : 1 for boolean member
immediate_echo.  Use ptrdiff_t for echo_after_prompt, since it's
a string length.
* keymap.c (push_key_description): Omit last arg, which was always 1.
All callers changed.

* lisp.h (enum pvec_type): Adjust comments and omit explicit
initializer for PVEC_NORMAL_VECTOR.

* termopts.h (flow_control, meta_key): Remove unused decls.
* dispnew.c, indent.c, nsterm.m, term.c, xsettings.c, xsmfns.c:
Don't include termopts.h.

select.el (xselect--encode-string): If a coding is specified for selection, and that is compatible with COMPOUND_TEXT, use it.

* window.el (switch-to-buffer-preserve-window-point): New option.
(switch-to-buffer): Obey
`switch-to-buffer-preserve-window-point' (Bug#4041).
