* print.c (print_preprocess): Adjust to match changed
sub char-table structure and avoid crash (Bug#18038).
+ * data.c (wrong_choice): Not static any more.
+ * lisp.h (wrong_choice): Add prototype.
+ * frame.h (struct frame) [USE_X_TOOLKIT || HAVE_NTGUI]:
+ Declare namebuf as such. Tweak comment.
+ [USE_GTK]: Likewise for tool_bar_position.
+ (fset_tool_bar_position) [USE_GTK]: Ditto.
+ (FRAME_TOOL_BAR_POSITION): New macro.

+ * xfns.c (Fx_create_frame): Use it.
+ (x_set_tool_bar_position): Add meaningful diagnostic messages.
