	* xdisp.c (display_line): Record maximum and minimum buffer
	positions even if no glyphs were produced (e.g., by a zero-width
	stretch).  Fixes bug#9530 on a TTY.  Under word-wrap, don't record
	buffer positions that will be removed from the glyph row because
	they don't fit.
8 9 10
	(produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
	column is beyond frame width: don't subtract 1 "pixel" when
	computing width of the stretch.

	at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.

	* xselect.c: Use signed conversions more consistently (Bug#9498).
	(selection_data_to_lisp_data): Assume incoming selection data are
	signed integers, not unsigned.  This is to be consistent with
	outgoing selection data, which was modified to use signed integers
	in as part of the fix to Bug#9196 in response to Jan D.'s comment
	in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11

	* fileio.c (Finsert_file_contents): If the file cannot be opened,
	set its "size" to -1.  This will set the modtime_size field of
	the corresponding buffer to -1, which is what
	verify-visited-file-modtime expects for files that do not exist.

	* keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
	here ...
	* lisp.h: ... from here.  push_key_description is no longer
	defined in keyboard.c, so its declaration should not be in
	lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
	logically belongs with push_key_description.

	isnan: Fix porting problem to Solaris 10 with bundled gcc.
	Without this fix, the command to link temacs failed due to an
	undefined symbol __builtin_isnan.  This is because
	/usr/include/iso/math_c99.h #defines isnan(x) to
	__builtin_isnan(x), but the bundled gcc, which identifies itself
	as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
	a __builtin_isnan.
	* floatfns.c (isnan): #undef, and then #define to a clone of
	what's in data.c.
	(Fisnan): Always define, since it's always available now.
	(syms_of_floatfns): Always define isnan at the Lisp level.

	* fileio.c: Fix bugs with large file offsets (Bug#9428).

	The previous code assumed that file offsets (off_t values) fit in
	EMACS_INT variables, which is not true on typical 32-bit hosts.
	The code messed up by falsely reporting buffer overflow in cases
	such as (insert-file-contents "big" nil 1 2) into an empty buffer
	when "big" contains more than 2**29 bytes, even though this
	inserts just one byte and does not overflow the buffer.
	(Finsert_file_contents): Store file offsets as off_t
	values, not as EMACS_INT values.  Check for overflow when
	converting between EMACS_INT and off_t.  When checking for
	buffer overflow or for overlap, take the offsets into account.
	Don't use EMACS_INT for small values where int suffices.
	When checking for overlap, fix a typo: ZV was used where
	ZV_BYTE was intended.
	(Fwrite_region): Don't assume off_t fits into 'long'.
	* buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.

	name_alist_or_stem is safe to alloca and fits in int.
	(Fexecute_extended_command): Likewise for function name and binding.
	(Frecursion_depth): Wrap around reliably on integer overflow.
	* keymap.c (push_key_description): First arg is now EMACS_INT, not int,
	since some callers pass EMACS_INT values.
	(Fsingle_key_description): Don't crash if symbol name contains more
	than MAX_ALLOCA bytes.
	* minibuf.c (minibuf_level): Now EMACS_INT, not int.

287 288
	Do not overrun buffer; instead, report string overflow.

289 290 291
	* dispnew.c (add_window_display_history): Don't overrun buffer.
	Truncate instead; this is OK since it's just a log.

292 293 294 295
	* editfns.c (Fcurrent_time_zone): Don't overrun buffer
	even if the time zone offset is outlandishly large.
	Don't mishandle offset == INT_MIN.

296 297 298
	* emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
	when creating daemon; the previous buffer-overflow check was incorrect.

299 300 301
	* eval.c (verror): Simplify by rewriting in terms of evxprintf,
	which has the guts of the old verror function.

302 303 304

	(font_unparse_xlfd): Don't blindly alloca long strings.
307
	Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
308
	fits in int, when using sprintf.  Use single snprintf to count
309 310 311 312 313 314
	length of string rather than counting it via multiple sprintfs;
	that's simpler and more reliable.
	(font_unparse_fcname): Use it to avoid sprintf buffer overrun.
	(generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
	sprintf, in case result does not fit in int.

315 316 317
	* fontset.c (num_auto_fontsets): Now printmax_t, not int.
	(fontset_from_font): Print it.

	* frame.c (tty_frame_count): Now printmax_t, not int.
	(make_terminal_frame, set_term_frame_name): Print it.
	(x_report_frame_params): In X, window IDs are unsigned long,
	not signed long, so print them as unsigned.
	(validate_x_resource_name): Check for implausibly long names,
	and don't assume name length fits in 'int'.
	(x_get_resource_string): Don't blindly alloca invocation name;

	in case result does not fit in int.

344 345 346 347 348 349 350 351
	* print.c (float_to_string): Detect width overflow more reliably.
	(print_object): Make sprintf buffer a bit bigger, to avoid potential
	buffer overrun.  Don't assume list length fits in 'int'.  Treat
	print length of 0 as 0, not as infinity; to be consistent with other
	uses of print length in this function.  Don't overflow print length
	index.  Don't assume hash table size fits in 'long', or that
	vectorlike size fits in 'unsigned long'.

352 353 354
	* process.c (make_process): Use printmax_t, not int, to format
	process-name gensyms.

355 356
