	* alloc.c: Catch some string size overflows that we were missing.
	(XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
	for convenience in STRING_BYTES_MAX.
	(STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
	The definition here is exact; the one in lisp.h was approximate.
	(allocate_string_data): Check for string overflow.  This catches
	some instances we weren't catching before.  Also, it catches
	size_t overflow on (unusual) hosts where SIZE_MAX <= min
	(PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
	and ptrdiff_t and EMACS_INT are both 64 bits.
	* character.c, coding.c, doprnt.c, editfns.c, eval.c:
	All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
	* lisp.h (STRING_BYTES_BOUND): Renamed from STRING_BYTES_MAX.

	All callers changed.  (Bug#8762)

	* gnutls.c: Use Emacs's memory allocators.
	Without this change, the gnutls library would invoke malloc etc.
	directly, which causes problems on non-SYNC_INPUT hosts, and which
	runs afoul of improving memory_full behavior.  (Bug#8761)
	(fn_gnutls_global_set_mem_functions): New macro or function pointer.
	(emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
	xfree instead of the default malloc, realloc, free.
	(Fgnutls_boot): No need to check for memory allocation failure,
	since xmalloc does that for us.

	(pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
	(Fformat): Avoid the prepass trying to compute sizes; it was only
	approximate and thus did not catch overflow reliably.  Instead, walk
	through the format just once, formatting and computing sizes as we go,
	checking for integer overflow at every step, and allocating a larger
	buffer as needed.  Keep track separately whether the format is
	multibyte.  Keep only the most-recently calculated precision, rather
	than them all.  Record whether each argument has been converted to
	string.  Use EMACS_INT, not int, for byte and char and arg counts.

	so that the resulting value does not suffer from catastrophic
	integer truncation.  For example, on a 64-bit host (* 4
	most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.

	Don't assume that the difference between two unsigned long values
	can fit into an integer.  At this point, we know button_down_time

	there's no need to cast the result if double-click-time is
	nonnegative, as it should be; check that it's nonnegative, just in
	case.  This bug is triggered when events are more than 2**31 ms

798 799 800
	* xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
	that always fit in int.  Use a sentinel instead of a counter, to
	avoid a temp and to allay GCC's concerns about possible int overflow.
801 802
	* frame.h (struct frame): Use int for menu_bar_items_used
	instead of EMACS_INT, since it always fits in int.

	* makefile.w32-in: The bootstrap-temacs rule now makes use of
	one of two shell specific rules, either bootstrap-temacs-CMD or
	bootstrap-temacs-SH.  The bootstrap-temacs-SH rule is identical
	to the previous implementation of the bootstrap-temacs rule.
	The bootstrap-temacs-CMD rule is similar to the previous
	implementation of the bootstrap-temacs rule except that it
	makes use of the ESC_CFLAGS variable instead of the CFLAGS
	variable.

	These changes, along with some changes to nt/configure.bat,
	nt/gmake.defs, and nt/nmake.defs, are required to extend my
	earlier fix to add support for --cflags and --ldflags options
	that include quotes so that it works whether make uses cmd or
	sh as the shell.

	(EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
	on 32-bit hosts that have 64-bit int, so that they can access
	large files.
966 967
	However, temporarily disable this change unless the temporary
	symbol WIDE_EMACS_INT is defined.

969 970
	* lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.

	Prefer intptr_t/uintptr_t for integers the same widths as pointers.
	This removes an assumption that EMACS_INT and long are the same
	width as pointers.  The assumption is true for Emacs porting targets
	now, but we want to make other targets possible.
	* lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
	(EMACS_INTPTR, EMACS_UINTPTR): New macros.
	In the rest of the code, change types of integers that hold casted
	pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
	replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
	(XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
	(XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
	No need to cast type when ORing.
	(XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
	* alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
	* doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
	assume EMACS_INT is the same width as char *.
	* gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
	(xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
	Remove no-longer-needed casts.
	(xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
	(xg_tool_bar_help_callback, xg_make_tool_item):
	Use EMACS_INTPTR to hold an integer
	that will be cast to void *; this can avoid a GCC warning
	if EMACS_INT is not the same width as void *.
	* menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
	* xdisp.c (display_echo_area_1, resize_mini_window_1):
	(current_message_1, set_message_1):
	Use a local to convert to proper width without a cast.
	* xmenu.c (dialog_selection_callback): Likewise.

1001 1002 1003 1004 1005 1006
	* sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
	Also, don't assume VALBITS / RAND_BITS is less than 5,

1007 1008 1009 1010 1011 1012 1013 1014
	* lread.c (hash_string): Use size_t, not int, for hash computation.
	Normally we prefer signed values; but hashing is special, because
	it's better to use unsigned division on hash table sizes so that
	the remainder is nonnegative.  Also, size_t is the natural width
	for hashing into memory.  The previous code used 'int', which doesn't
	retain enough info to hash well into very large tables.
	(oblookup, oblookup_last_bucket_number, Funintern): Likewise.

1015 1016 1017 1018 1019
	* dbusbind.c: Don't possibly lose pointer info when converting.
	(xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
	Use XPNTR rather than XHASH, so that the high-order bits of
	the pointer aren't lost when converting through void *.

	* lisp.h: Fix a problem with aliasing and vector headers.  (Bug#8546)
1260 1261
	GCC 4.6.0 optimizes based on type-based alias analysis.
	For example, if b is of type struct buffer * and v of type struct
1262 1263 1264 1265 1266
	Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
	!= &v->size, and therefore "v->size = 1; b->size = 2; return
	v->size;" must therefore return 1.  This assumption is incorrect
	for Emacs, since it type-puns struct Lisp_Vector * with many other
	types.  To fix this problem, this patch adds a new type struct

1312 1313 1314 1315 1316 1317 1318 1319 1320 1321
	* data.c (atof): Remove decl; no longer used or needed.
	(digit_to_number): Move to lread.c.
	(Fstring_to_number): Use new string_to_number function, to be
	consistent with how the Lisp reader treats infinities and NaNs.
	Do not assume that floating-point numbers represent EMACS_INT
	without losing information; this is not true on most 64-bit hosts.
	Avoid double-rounding errors, by insisting on integers when
	parsing non-base-10 numbers, as the documentation specifies.
	* lisp.h (string_to_number): New decl, replacing ...
	(isfloat_string): Remove.
1322
	* lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.

	(read1): Do not accept +. and -. as integers; this
1324 1325 1326 1327 1328 1329 1330
	appears to have been a coding error.  Similarly, do not accept
	strings like +-1e0 as floating point numbers.  Do not report
	overflow for integer overflows unless the base is not 10 which
	means we have no simple and reliable way to continue.
	Break out the floating-point parsing into a new
	function string_to_number, so that Fstring_to_number parses
	floating point numbers consistently with the Lisp reader.

	This function checks for valid syntax and produces the resulting
	Lisp float number too.  Rework it so that string-to-number
1337
	no longer mishandles examples like "1.0e+".  Use strtoumax,
1338 1339
