+
+        Add lexical binding.
+
+        * window.c (Ftemp_output_buffer_show): New fun.
+        (Fsave_window_excursion):
+        * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
+
+        * lread.c (lisp_file_lexically_bound_p): New function.
+        (Fload): Bind Qlexical_binding.
+        (readevalloop): Remove `evalfun' arg.
+        Bind Qinternal_interpreter_environment.
+        (Feval_buffer): Bind Qlexical_binding.
+        (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
+        Mark as dynamic.
+        (syms_of_lread): Declare `lexical-binding'.
