gnus-msg.el (gnus-msg-mail): Make it avoid using posting styles corresponding to any existing group (Bug#14166)

This bug was introduced in 2012-10-15T09:03:56Z!rudalics@gmx.at
while solving bug #12600.

 src/window.c (Fwindow_end): Test more flags, including the buffer's
 last_overlay_modified flag, to determine whether the window's
 display is really up-to-date.  Prevents the function from
 returning a stale value.
 (Fwindow_line_height): Fix the test for up-to-date-ness of the
 current matrix.

 src/frame.c (do_switch_frame): Mark the TTY frame we switch to as
 garbaged only if it is not already the top frame on its TTY.  This
 prevents flickering due to constant redrawing of TTY frames when
 there are GUI frames open in the same session.

of marking the idle timers directly.
* lisp/emacs-lisp/timer.el (timer--check): New function.
(timer--time, timer-set-function, timer-event-handler): Use it.
(timer-set-idle-time): Simplify.
(timer--activate): CSE.
(timer-event-handler): Give more info in error message.
(internal-timer-start-idle): New function, moved from C.

(mpc-proc-cmd): Use it.
(mpc--status-timer-run): Also catch signals from `mpc-proc'.
(mpc-status-buffer-show, mpc-tagbrowser-dir-toggle): Call `mpc-proc'
less often.

`add-log-current-defun-function'.
(sh-current-defun-name): New function.
(sh-mode): Use the function.

* nt/emacs.rc: Use 64-bit manifest for 64-bit Cygwin build.

* configure.ac (W32_RES_LINK): Remove unnecessary linker directive
`-Wl,-bpe-i386', which is confusing in the 64-bit case.

* fileio.c (ACL_NOT_WELL_SUPPORTED): New macro copied from gnulib.
(Fcopy_file, Fset_file_acl) [HAVE_POSIX_ACL]: Use it.

f->output_data.ns.

This bug was introduced by my 2013-02-25 change that simplified
data_start configuration.  Without this change, on GNU/Linux
an Emacs configured with --enable-profiling fails immediately
due to a profiler signal.
* configure.ac (LD_SWITCH_SYSTEM_TEMACS): Append -pg if profiling
and if not on GNU/Linux or FreeBSD.
* lib/Makefile.am (AM_CFLAGS): Add $(PROFILING_CFLAGS), so that
lib/*.o is profiled too.
* src/Makefile.in: Compile with $(PROFILING_CFLAGS), but do not link
with these flags.  On platforms where special flags are needed
when linking temacs, the flags are now in LD_SWITCH_SYSTEM_TEMACS.
(ALL_CFLAGS): Remove $(PROFILING_CFLAGS).
(.c.o, .m.o): Compile with $(PROFILING_CFLAGS).

system and its capabilities.  This is a partial rework of the
2013-04-05 change.
* lisp.h (have_menus_p): Remove prototype.  This function is
replaced with platform-independent window_system_available.
(check_window_system): Move to...
* frame.h (decode_window_system_frame, window_system_available):
...here, add new prototypes.
* frame.c (window_system_available, decode_window_system_frame):
New functions.
(check_window_system): Platform-independent now.
* xterm.h (x_in_use): Remove declaration.
(check_x_frame):
* w32term.h (check_x_frame):
* nsterm.h (check_x_frame): Remove prototypes.  This function
is replaced with platform-independent decode_window_system_frame.
* msdos.c (have_menus_p): Remove.
* nsfns.m (check_window_system, have_menus_p, check_ns_frame):
Remove platform-specific functions.  Use check_window_system,
decode_window_system_frame and check_ns_display_info where
appropriate.  Minor style and comment tweaks.
* w32fns.c (w32_in_use, check_window_system, have_menus_p)
(check_x_frame): Likewise.
* xfns.c (x_in_use, check_window_system, have_menus_p, check_x_frame):
Likewise.
* fileio.c, fns.c, font.c, fontset.c, image.c, menu.c, nsmenu.m:
* nsselect.m, nsterm.m, w32font.c, w32menu.c, xfaces.c, xgselect.c:
* xmenu.c, xselect.c: All related users changed.

This is needed to prevent from weird situation described at
<http://lists.gnu.org/archive/html/emacs-devel/2013-04/msg00212.html>.
* frame.el (make-frame): Set x-display-name after call to
window system initialization function, not before.
* term/x-win.el (x-initialize-window-system): Add optional
display argument and use it.
* term/w32-win.el (w32-initialize-window-system):
* term/ns-win.el (ns-initialize-window-system):
* term/pc-win.el (msdos-initialize-window-system):
Add compatible optional display argument.

 lisp/files.el (normal-backup-enable-predicate): On MS-Windows and
 MS-DOS compare truenames of temporary-file-directory and of the
 file, so that 8+3 aliases (usually found in $TEMP on Windows)
 don't fail comparison by compare-strings.  Also, compare file
 names case-insensitively on MS-Windows and MS-DOS.

* display.texi (Faces): Minor clarifications.
(Defining Faces): Clarify default vs custom face specs.  Document
face-spec-set.

* display.texi (Overlay Properties):
* text.texi (Special Properties): Use the "anonymous face"
terminology.  Describe foreground-color and background-color forms
as compatibility-only.
