typo in gtkselection.[hc] ?

[acano systec com]

In gtkselection.h:

typedef struct _GtkSelectionData GtkSelectioData;
                                            ^-------- where's the 'n'?

Then in gtkselection.c a (GtkSelectioData *) is returned:

GtkSelectioData*
gtk_selection_data_copy (GtkSelectionData *data)
{
  GtkSelectionData *new_data;
  ...
}


Everything else uses GtkSelectionData.

Looks like you get away with it because gtkselection.h
includes gtkwidget.h which has:

typedef struct _GtkSelectionData GtkSelectionData;

Is it just a typo?
