WAC charts from the 1990s show _both_ symbols with the following descriptions in the legend.
Broken circle: "Unlicensed Aerodromes. Named in purple. Status and Serviceability Unknown"
Circle with U : "Aerodrome Landmark (unusable)"

It also seems that around 2003/4ish the description on the broken circle symbol on VTCs etc went from "Non Licensed Aerodrome (status unknown)" to "Aerodrome (Not Certified or Registered)"
