child-handling code so that it initializes its private SIGCHLD handler.
* syssignal.h (SA_SIGINFO): Default to 0.

Fix bug #14558 with turning off mouse-highlight during highlight.

 don't insist on being invoked on a highlighted tool-bar button.
 Avoids losing tool-bar functionality when mouse-highlight is nil.
 (note_tool_bar_highlight, note_mode_line_or_margin_highlight):
 Don't highlight when mouse-highlight is nil.
 (note_mouse_highlight): When mouse-highlight is nil, don't return
 right away; instead, run tool-bar and mode-line highlight
 subroutine, clear any existing highlight, and revert the mouse
 pointer to its default shape.
        * isearch.el (isearch-allow-prefix): New user option.
        (isearch-other-meta-char): don't exit isearch when a prefix
        argument is typed whilst `isearch-allow-prefix' is non-nil.

        (Net Exiting Isearch): Document new user option
        `isearch-allow-prefix'.

	* etc/NEWS.  Entry for this change.
Add bug#9706.
* isearch.el (isearch-allow-prefix): New defcustoms need :version tags
(chisel this on my tombstone)
A few porting etc. fixes for the new file monitor code.

See the thread containing
<http://lists.gnu.org/archive/html/emacs-devel/2013-06/msg00109.html>.
* gfilenotify.c (dir_monitor_callback, Fgfile_add_watch)
(Fgfile_rm_watch): Don't assume EMACS_INT is the same width as a pointer.
(dir_monitor_callback, Fgfile_rm_watch):
Use assq_no_quit instead of Fassoc, for speed.
(dir_monitor_callback, Fgfile_rm_watch):
eassert that the monitor is a fixnum.
(dir_monitor_callback): No need for CDR_SAFE.
Simplify building of lisp with alternative tails.
(Fgfile_add_watch, Fgfile_rm_watch):
Do not assume glib functions set errno reliably on failure.
(Fgfile_add_watch): Check that the monitor survives the XIL trick,
and signal an error otherwise.
(Fgfile_rm_watch): Prefer CONSP to !NILP.
Use Fdelq instead of Fdelete, for speed.
