* etc/NEWS: Document it.
* lisp/emacs-lisp/timer.el (timer): PSECS is now at the end, rather than
being right after USECS, as that better supports old code that
inadvisedly looked directly at the timer vector.
* src/keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
vector element, not from the 4th, since PSECS is now at the end.
(Fcurrent_idle_time): Doc fix.
Fixes: debbugs:12430
* etc/NEWS: Document timer format change.
* lisp/image.el (image-animate-timer):
* lisp/time.el (display-time-world-timer):
Use timer--function and timer--args rather than raw access to
timer vector.
* lisp/gnus/gnus-art.el (gnus-article-stop-animations):
Use timer--function rather than raw access to timer vector.

The code that dealt with SIGIO was crufty and confusing, e.g., it
played tricks like "#undef SIGIO" but these tricks were not used
consistently. Simplify mostly by not #undeffing standard symbols,
e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
or not as we please) rather than "defined SIGIO" (standard symbol
that we probably shouldn't #undef).
* configure.ac (NO_TERMIO, BROKEN_FIONREAD, BROKEN_SIGAIO)
(BROKEN_SIGPOLL, BROKEN_SIGPTY): Remove.
(USABLE_FIONREAD, USABLE_SIGIO): New symbols. All uses of
'defined SIGIO' replaced with 'defined USABLE_SIGIO', with no need
to #undef SIGIO now (which was error-prone). Likewise, all uses
of 'defined FIONREAD' replaced with 'defined USABLE_FIONREAD'.
* src/admin/CPP_DEFINES (BROKEN_SIGAIO, BROKEN_SIGIO, BROKEN_SIGPOLL)
(BROKEN_SIGPTY, NO_TERMIO): Remove.
* src/conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
Modules that need it can include it.
[USG5_4 && emacs]: Likewise, do not include the streams stuff here.
* src/dispextern.h (ignore_sigio): New decl.
* src/emacs.c (shut_down_emacs): Invoke unrequest_sigio
unconditionally, since it's now a no-op if !USABLE_SIGIO.
* src/emacs.c (shut_down_emacs):
* src/keyboard.c (kbd_buffer_store_event_hold):
Use ignore_sigio rather than invoking 'signal' directly.
* src/keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
for FIONREAD.
(FIONREAD, SIGIO): Do not #undef.
(tty_read_avail_input): Use #error rather than a syntax error.
* src/process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
for I_PIPE, used by SETUP_SLAVE_PTY.
(DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
* src/sysdep.c (croak): Remove; no longer needed. This bit of
temporary code, with Fred N. Fish's comment that it's temporary,
has been in Emacs since at least 1992!
(init_sigio, reset_sigio, request_sigio, unrequest_sigio):
Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
* src/syssignal.h (croak): Remove decl.
(SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
* src/systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
now that we're termios-only.
(FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
* src/term.c (dissociate_if_controlling_tty): Use #error rather than
a run-time error.

Remove the "edebug-" prefix from non-dynamically-scoped variables.
Mark unused args with underscore.
(edebug-save-restriction, edebug-outside-excursion): Use `declare'.
(edebug-form-data): Use defvar-local.
(edebug-make-before-and-after-form, edebug-make-after-form):
Use backquote.

(edebug--update-coverage): Add `after-index' and `value' args.
Rename from edebug-update-coverage.
(edebug-slow-after): Call it accordingly.
(edebug--recursive-edit): Add arg `arg-mode'. Rename from
edebug-recursive-edit.
(edebug--display): Call it accordingly. Add args `value',

* emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
to work around GNOME bug 683906.
* image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
(struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
This works around GCC bug 54561.
* eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
* image.c (struct png_load_context) [HAVE_PNG]: New type.
(png_load_body) [HAVE_PNG]:
(jpeg_load_body) [HAVE_JPEG]:
New function, with most of the old parent function's body.
(png_load) [HAVE_PNG]:

Invoke the new function, to avoid longjmp munging our locals.
(struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
(my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
longjmp is passed 2, as the C standard doesn't guarantee this.
Instead, store the failure code into mgr->failure_code.

* lisp/info.el (Info-search): Don't check for isearch-mode and
isearch-regexp before let-binding search-spaces-regexp to
Info-search-whitespace-regexp.
(Info-isearch-search): Let-bind Info-search-whitespace-regexp to
search-whitespace-regexp if isearch-lax-whitespace or
isearch-regexp-lax-whitespace is non-nil.
(Info-mode): Don't set local variable search-whitespace-regexp.
and then gtk2 if not found.

* lisp/emacs-lisp/debug.el (debugger-outer-unread-command-char, debug)
(debugger-env-macro): Remove support for unread-command-char.
* lisp/ehelp.el (with-electric-help): Accept functions in
electric-help-form-to-execute.
(electric-help-execute-extended, electric-help-ctrl-x-prefix): Use it.
And replace unread-command-char -> unread-command-events.
* lisp/subr.el (set-temporary-overlay-map): Minimize slightly the impact of
the temporary map re-appearing on emulation-mode-map-alists.
* lisp/emacs-lisp/edebug.el (def-edebug-form-spec): Remove, it's been broken
since 22.1.
src/w32proc.c (sys_kill): If PID is our process ID and the signal is
SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
violation. (Bug#12426)
* emacs-lisp/debug.el (debugger-previous-window-height): New
variable.
(debug): When debugger-jumping-flag is non-nil try to restore
height of debugger window. (Bug#8789)
overriding-local-map and pre/post-command-hook here.
(edebug-recursive-edit): Do it here instead.
(edebug-outside-unread-command-char): Remove all uses of
unread-command-char.

If a nonvolatile local variable is written before a _longjmp to
the frame containing the variable, and is read after the _longjmp,
the value read is indeterminate. Some local variables of type
'struct handler' and 'struct catchtag' are used in this way, so
mark each of their slots as volatile if the slot can be set before
_longjmp and read afterwards.
* lisp.h (struct handler): var and chosen_clause are now volatile.
(struct catchtag): val, next, and pdlcount are now volatile.
* lib-src/pop.c (socket_connection) [HAVE_GETADDRINFO]:
* src/bidi.c (bidi_push_it, bidi_pop_it):
* src/fns.c (copy_hash_table):
* src/image.c (define_image_type):

* src/process.c (Fprocess_send_eof):
* src/xfaces.c (x_create_gc) [HAVE_NS]:
* src/xgselect.c (xg_select):
Use assignment, not memcpy, as either will do here, and assignment is
more likely to catch type errors.
Use pointer-to-a-pointer to simplify and avoid a NILP check each
time an item is removed. No need to mark this function 'inline';
the compiler knows better than we do.
* nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
(updateFrameSize:): Add delay parameter to updateFrameSize, send it
to change_frame_size.
(windowDidResize:): Pass YES to updateFrameSize.

This reduces an amount of references to killed buffers and
helps GC to reclaim them faster.
* alloc.c (discard_killed_buffers): New function.
(mark_object): Use it for deleted windows and frames.
(mark_object): If symbol's value is set up for a killed buffer
or deleted frame, restore it's global binding.
* data.c (swap_in_global_binding): Add GC notice.
(swap_in_symval_forwarding): Use convenient set_blv_where.
* window.c (wset_next_buffers, wset_prev_buffers): Move ...
* window.h: ... to here.
* Makefile.in (install-arch-dep, install-arch-indep, install-doc):
Be more explicit about dependencies, for parallel `make install'.
It is not so unreasonable to run `make -j# install' from a clean state
for a self-contained NS build, where the "installation" happens within
the build tree.
The porting part of this patch fixes bugs on non-IEEE platforms
with frexp, ldexp, logb.
* admin/CPP-DEFINES (HAVE_CBRT, HAVE_LOGB, logb): Remove.
* configure.ac (logb, cbrt): Do not check for these functions,
as they are not being used.
* doc/lispref/numbers.texi (Float Basics, Arithmetic Operations, Math Functions):
Document that / and mod (with floating point arguments), along
with asin, acos, log, log10, expt and sqrt, return special values
instead of signaling exceptions.
(Float Basics): Document that logb operates on the absolute value
of its argument.
(Math Functions): Document that (log ARG BASE) also returns NaN if
BASE is negative. Document that (expt X Y) returns NaN if X is a
finite negative number and Y a finite non-integer.
* etc/NEWS: Document NaNs versus signaling-error change.
* src/data.c, src/lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
Now static.
* src/floatfns.c: Simplify discussion of functions that Emacs doesn't
support, by removing commented-out code and briefly listing the
C89 functions excluded. The commented-out stuff was confusing
maintenance, e.g., we thought we needed cbrt but it was commented out.
(logb): Remove decl; no longer needed.
(isfinite): New macro, if not already supplied.
(isnan): Don't replace any existing macro.
(Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
are present on all C89 platforms.
(Ffrexp): Do not special-case zero, as frexp does the right thing
for that case.
(Flogb): Do not use logb, as it doesn't have the desired meaning
on hosts that use non-base-2 floating point. Instead, stick with
frexp, which is C89 anyway. Do not pass an infinity or a NaN to
frexp, to avoid getting an unspecified result.
