We had a bit of a discussion about this in our company recently and the position of the tech. management was that there were various possible errors in the wind computation, especially at low level or when crossed controls were being used. Because of this, wind readouts were deemed "advisory", so a G/A was not mandatory if they were out-of-limits but the tower winds were OK.
That said, I think it'd be unwise to ignore this information - personally I'd give serious consideration to throwing it away if the wind component was significantly outside book figures, as I might be experiencing something that was shortly to be reported.
