+
++ * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
++ concerns.
++
++ * term.c (produce_glyphless_glyph): Remove unnecessary test.
++
++ * cm.c (calccost): Turn while-do into do-while, for clarity.
+
+ * keyboard.c (syms_of_keyboard): Use the same style as later
+ in this function when indexing through an array. This also
+ works around GCC bug 48267.
+
+ * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
+
+ * xselect.c (x_check_property_data): Return correct size (Bug#8335).
+
-2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
+ * chartab.c (sub_char_table_ref_and_range): Redo for slight
+ efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
- * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
- concerns.
+ * keyboard.c, keyboard.h (num_input_events): Now size_t.
+ This avoids undefined behavior on integer overflow, and is a bit
+ more convenient anyway since it is compared to a size_t variable.
- * chartab.c (sub_char_table_ref_and_range): Redo to avoid overflow
- concerns.
+ Variadic C functions now count arguments with size_t, not int.
+ This avoids an unnecessary limitation on 64-bit machines, which
+ caused (substring ...) to crash on large vectors (Bug#8344).
+ * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
+ (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
+ All variadic functions changed accordingly.
+ (struct gcpro.nvars): Now size_t, not int. All uses changed.
+ * data.c (arith_driver, float_arith_driver): Likewise.
+ * editfns.c (general_insert_function): Likewise.
+ * eval.c (struct backtrace.nargs, interactive_p)
+ (internal_condition_case_n, run_hook_with_args, apply_lambda)
+ (funcall_lambda, mark_backtrace): Likewise.
+ * fns.c (concat): Likewise.
+ * frame.c (x_set_frame_parameters): Likewise.
+ * fns.c (get_key_arg): Now accepts and returns size_t, and returns
+ 0 if not found, not -1. All callers changed.
- * term.c (produce_glyphless_glyph): Remove unnecessary test.

- * cm.c (calccost): Turn while-do into do-while, for clarity.
+ * alloc.c (garbage_collect): Don't assume stack size fits in int.
+ (stack_copy_size): Now size_t, not int.
+ (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

+ * syssignal.h: Replace RETSIGTYPE with void.
+ * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
+ * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
+ Replace SIGTYPE with void everywhere.
+ * s/usg5-4-common.h (SIGTYPE): Remove definition.
+ * s/template.h (SIGTYPE): Remove commented out definition.

+
+ * xdisp.c (redisplay_window): Don't check buffer's clip_changed
+ flag as a prerequisite for invoking try_scrolling. (Bug#6671)
