src/w32fns.c (CaptureStackBackTrace_proc): New typedef.
(BACKTRACE_LIMIT_MAX): New macro.
(w32_backtrace): New function.
(emacs_abort): Use w32_backtrace when the user chooses not to
attach a debugger. Update the text of the abort dialog.
* termhooks.h (struct input_event): Remove padding field.
Adjust comment.
* keyboard.c (event_to_kboard): Simplify because frame_or_window
member is never cons for a long time. Adjust comment.
(mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
* xterm.c (handle_one_xevent): Do not initialize frame_or_window
field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
* doc/misc/cl.texi: More copyedits, plus:
(Time of Evaluation, Iteration): Add xref to Emacs Lisp manual.
(Macro Bindings, Blocks and Exits): Acknowledge existence of lexical-binding.
(Iteration): Mainly defer to doc of standard dolist, dotimes.
* doc/lispref/eval.texi (Special Forms): No longer special forms:
defmacro, defun, save-window-excursion, with-output-to-temp-buffer.
* doc/lispref/functions.texi (Defining Functions): Defun is now a macro.
Defalias is a function.
* callproc.c (setpgrp): Remove macro, as we now use setpgid
and it is configured in conf_post.h.
(Fcall_process): Don't invoke both setsid and setpgid; the former
is enough, if it exists.
* callproc.c (Fcall_process, child_setup):
* process.c (create_process): Use setpgid.
* conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
for the real thing.
* dispnew.c (init_display): Initialize the foreground group
if we are running a tty display.
* emacs.c (main): Do not worry about setpgrp; init_display does it now.
* lisp.h (init_foreground_group): New decl.
* sysdep.c (inherited_pgroup): New static var.
(init_foreground_group, tcsetpgrp_without_stopping)
(narrow_foreground_group, widen_foreground_group): New functions.
(init_sys_modes): Narrow foreground group.
(reset_sys_modes): Widen foreground group.
Fixes: debbugs:12697
* window.el (quit-restore-window): If the window has been
created on an existing frame and ended up as the sole window on
that frame, do not delete it (Bug#12764).
* minibuf.c (read_minibuf): Restore current buffer since
choose_minibuf_frame calling Fset_frame_selected_window may
change it (Bug#12766).
* doc/misc/cl.texi (Function Bindings): Update for cl-flet and cl-labels.
(Obsolete Lexical Binding): Rename section from "Lexical Bindings".
(Obsolete Macros): Rename section from "Obsolete Lexical Macros".
Reword, and add details of flet and labels.
* etc/NEWS: Related markup.
Fixes: debbugs:12760
* doc/misc/cl.texi (Modify Macros): Update for cl-letf changes.
(Obsolete Lexical Macros): Say a little more about letf/cl-letf.
* lisp/emacs-lisp/cl.el (letf): Doc fix.
* etc/NEWS: Related edit.
cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode): In
preparation for fixing bug#12739, move these functions from
here...
* coding.h, coding.c: ... to here, and compile them only when
WINDOWSNT or HAVE_NTGUI. Moving these functions out of cygw32
proper lets us write cygw32-agnostic code for the HAVE_NTGUI case.
