	(CHAR_TABLE_STANDARD_SLOTS, CHAR_TABLE_EXTRA_SLOTS):

	Improve GDB symbol export (Bug#12036).
	* .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different

	* alloc.c (gdb_make_enums_visible): New constant.  This ports to
	GCC 3.4.2 the export of symbols to GDB.  Problem reported by Eli
	Zaretskii in <http://bugs.gnu.org/12036#13>.
	* lisp.h (PUBLISH_TO_GDB): Remove.  All uses removed.  No longer
	needed now that we have gdb_make_enums_visible.

	New enum types, packaging up enums that need to be exported to GDB.

	(ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from

	the fix for 12036 would have avoided some of the problems noted in

	(GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
	(CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.

	* .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
	$bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
	(xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
	Adjust to changes in lisp.h and emacs.c, by using
	CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
	of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
	INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
	gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
	instead of gdb_valbits.
	(xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
	PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
	instead of gdb_array_mark_flag.
	(xboolvector): Get size from $->size, not $->header.size.
	Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.

	(ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
	as constants, so they're visible to GDB.

	(PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
	Now enum constants, not macros, so they're visible to GDB.
	(CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
	more convenient now.  All uses changed.
	(VALMASK) [USE_LSB_TAG]: Also define in this case.
	* mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.

	Use typedef for EMACS_INT, EMACS_UINT.
	* lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
	than macros.  This simplifies debugging in the usual case, since
	it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
	and it allows expressions involving EMACS_INT casts.
	* .gdbinit (xreload): Simplify by using EMACS_INT cast.

	Adjust buffer text indirection counters at the end of Fkill_buffer.
	* buffer.c (Fkill_buffer): Adjust indirection counters when the
	buffer is definitely dead.  This should really fix an issue reported
	by Christoph Scholtes again.  (Bug#12007).
	(init_buffer_once): Initialize indirection counters of
	buffer_defaults and buffer_local_symbols (for sanity and safety).

	EMACS_TIME simplification (Bug#11875).
	This replaces macros (which typically do not work in GDB)
	with functions, typedefs and enums, making the code easier to debug.
	The functional style also makes code easier to read and maintain.
	* systime.h: Include <sys/time.h> on all hosts, not just if
	WINDOWSNT, since 'struct timeval' is needed in general.
	(EMACS_TIME): Now a typedef, not a macro.
	(EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
	not macros.

	Don't warn if site-lisp directories are missing.

	PATH_LOADSEARCH refers to the eventual installation directories.

	glyphs.
	(insert_left_trunc_glyphs): Support GUI frames: make sure
	truncation glyphs overwrite enough glyphs from the current line to
	have sufficient space in pixels.
	(display_line): Support truncation and continuation glyphs on GUI
	frames.  If some spare pixels are left on the line after inserting

	All callers changed.

	Port to OpenBSD 5.1 amd64.
	* sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
	This is needed for OpenBSD, and should be harmless on all BSD systems.
	Also, include <sys/sysctl.h>, as it should be available on all
	BSD_SYSTEM hosts given that we're already calling sysctl in that case.
	(list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
