+       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.

        * alloc.c (garbage_collect): Don't assume stack size fits in int.
