This type of modification isn't meant to be binary compatible in both
directions.  Your Pd-Vanilla externals with the Vanilla
t_widgetbehavior struct will not work in Pd-l2ork, because the struct
is smaller.

When Pd-l2ork tries to access those elements off the end of the
t_widgetbehavior struct, it should seg fault.
