By default it does have the same settings, but in multiple themes it
does not.

That is exactly what the code above tries to achieve.  I briefly looked
at the Windows theme source code and figured that it does things a little
different than the theme engine I first looked at.  Does using:

  style = gtk_rc_get_style_by_paths (gtk_widget_get_settings (button),
                                     "*.GtkTreeView.GtkButton",
                                     "*.GtkTreeView.GtkButton",
                                     G_OBJECT_TYPE (button));

instead of the call to gtk_rc_get_style_by_paths() posted earlier have
any effect?
