	include those frames as candidates which have their focus
	redirected to the minibuffer frame.

	* fns.c (Fputhash): Return `value' rather than nil.

2000-06-30  Gerd Moellmann  <gerd@gnu.org>

	* frame.c (next_frame): Don't check focus redirection in case
	MINIBUF is a window.  Doing so excludes frames using MINIBUF
	unless their focus is redirected, which contradicts the
	specification of next-frame, and leads to infinite loops in
	certain situations when cycling through windows with next-window.

2000-06-30  Kenichi Handa  <handa@etl.go.jp>

	* coding.c (code_convert_region): Even if the length of text is

	(add_row_entry): New function.
	(scrolling_window): Use data structures allocated with xmalloc and
	held in global variables, instead of allocating them with alloca and
	holding them in local variables.  Use a larger hash table whose
	size depends on glyph matrix sizes.  Don't use bzero to clear the
	hash table; instead, clear used slots only.

	Frun_hook_with_args count argument.

	* xterm.c (x_send_scroll_bar_event): Fudge lisp object/integer

	* atimer.c (alarm_signal_handler): Add forward declaration.

	* data.c (set_internal): Remove debug code.

2000-06-14  Gerd Moellmann  <gerd@gnu.org>

	* Makefile.in (bootstrap-temacs): Add `-I../src'.

	to `XEvent *'.

2000-06-10  Kenichi Handa  <handa@etl.go.jp>

	* regex.c (MAKE_CHAR) [!emacs]: Dummy macro for non-Emacs env.
	(regex_compile): Fix the code for handling the case of single byte

	* xterm.c (XTread_socket) <FocusIn>: Queue a FOCUS_IN_EVENT which
	will be translated to a switch-frame event when reading the
	event queue.  This is necessary because Emacs otherwise won't
	perform a switch-frame to a new frame until some other event, for
	example a keystroke event, forces it to do so.  This has various
	effects, one visible being that the cursor of a frame created with
	C-x 5 2 or switched to with a window manager key binding like
	A-TAB stays hollow because selected_window isn't on the newly
	focused frame until the switch-frame is performed.

	* keyboard.c (kbd_buffer_get_event): Handle FOCUS_IN_EVENT by
	generating a switch-frame event if necessary.

	* termhooks.h (enum event_kind): Add FOCUS_IN_EVENT.

	on_failure_jump_smart&jump instead of
	on_failure_jump&maybe_pop_jump.  Change + loops to eliminate the
	initial (dummy_failure_)jump.  Remove c1_base (looks like unused
	variable to me).  Use `jump' instead of `jump_past_alt' and don't
	bother with push_dummy_failure in alternatives since it is now
	unnecessary.  Use FIXUP_ALT_JUMP.  Eliminate a useless `#ifdef
	emacs' for (re)allocating the stack.
	(re_compile_fastmap): Remove dead variables i and num_regs.  Exit
	from loop when bufp->can_be_null rather than jumping to `done'.
	Avoid jumping backwards so as to ensure termination.  Use
	PATTERN_STACK_EMPTY and POP_PATTERN_OP.  Improved handling of
	backreferences.  Remove dead code in handling of `anychar'.
	(skip_noops, mutually_exclusive_p): New functions taken from the
	handling of `maybe_pop_jump' in re_match_2_internal.  Slightly
	improve mutually_exclusive_p to handle ".+\n".
	(lowest_active_reg, highest_active_reg,
	NO_(LOWEST|HIGHEST)_ACTIVE_REG) Remove.
	(re_match_2_internal): Use %p instead of 0x%x when printf'ing
	ptrs.  Don't SET_REGS_MATCHED anymore.  Remove many dead
	variables.  Push register (in `start_memory') on the stack rather
	than storing it in old_reg(start|end).  Remove the cycle detection
	from `stop_memory', replaced by the use of on_failure_jump_loop
	for greedy loops.  Add code for the new on_failure_jump_<foo>.
	Remove ad-hoc code in `on_failure_jump' to push more registers in
	the case of a loop.  Take out code from `maybe_pop_jump' into
	separate functions and adapt it to the semantics of
	`on_failure_jump_smart'.  Remove jump_past_alt, dummy_failure_jump
	and push_dummy_failure.  Remove dummy_failure handling and
	handling of `failures to jump to on_failure_jump' (this last one
	was already dead code, it seems).
	(group_match_null_string_p, alt_match_null_string_p)
	(common_op_match_null_string_p): Remove.
