 +
 +	* xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
 +	not to EMACS_INT, to avoid GCC warning.
 +
 +	* xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
 +
 +	* buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
 +	The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
 +	isn't needed on 32-bit machines.
 +
 +	* buffer.c (Fgenerate_new_buffer_name): Use EMACS_INT for count, not int.
 +	(advance_to_char_boundary): Return EMACS_INT, not int.
 +
 +	* data.c (Qcompiled_function): Now static.
 +
 +	* window.c (window_body_lines): Now static.
 +
 +	* image.c (gif_load): Rename local to avoid shadowing.
 +
 +	* lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
 +	(struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
 +	* alloc.c (make_save_value): Integer argument is now of type
 +	ptrdiff_t, not int.
 +	(mark_object): Use ptrdiff_t, not int.
 +	* lisp.h (pD): New macro.
 +	* print.c (print_object): Use it.
 +
 +	* alloc.c: Use EMACS_INT, not int, to count objects.
 +	(total_conses, total_markers, total_symbols, total_vector_size)
 +	(total_free_conses, total_free_markers, total_free_symbols)
 +	(total_free_floats, total_floats, total_free_intervals, total_intervals)
 +	(total_strings, total_free_strings):
 +	Now EMACS_INT, not int.  All uses changed.
 +	(Fgarbage_collect): Compute overall total using a double, so that
 +	integer overflow is less likely to be a problem.  Check for overflow
 +	when converting back to an integer.
 +	(n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
 +	(n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
 +	These were 'int' variables that could overflow on 64-bit hosts;
 +	they were never used, so remove them instead of repairing them.
 +	(nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
 +	(inhibit_garbage_collection): Set gc_cons_threshold to max value.
 +	Previously, this ceilinged at INT_MAX, but that doesn't work on
 +	64-bit machines.
 +	(allocate_pseudovector): Don't use EMACS_INT when int would do.
 +
 +	* alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
 +	(allocate_vectorlike): Check for ptrdiff_t overflow.
 +	(mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
 +	when a (possibly-narrower) signed value would do just as well.
 +	We prefer using signed arithmetic, to avoid comparison confusion.
 +
 +	* 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.
 +
 +	* character.c (string_escape_byte8): Fix nbytes/nchars typo.
 +
 +	* alloc.c (Fmake_string): Check for out-of-range init.

+ 
+ 	* dispextern.h (struct image): Replace data member, whose int_val
+ 	and ptr_val fields were not used by anything, with a single
+ 	lisp_val object.
+ 
+ 	* image.c (Fimage_metadata, make_image, mark_image, tiff_load)
+ 	(gif_clear_image, gif_load, imagemagick_load_image)
+ 	(gs_clear_image, gs_load): Callers changed.

  	* buffer.h: Include <time.h>, for time_t.
