+
+ Fix more problems found by GCC 4.6.0's static checks.

+ Remove unused local var.
+
+ * editfns.c (Fmessage_box): Remove unused local var.
+
+ * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
+ (note_mode_line_or_margin_highlight, note_mouse_highlight):

+ * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:

+
+ * keyboard.c (parse_modifiers_uncached, parse_modifiers):

+ instead of alloca (Bug#8344).

+
+ * cm.c (calccost): Turn while-do into do-while, for clarity.
+
+ * keyboard.c (syms_of_keyboard): Use the same style as later
