I like the idea of trying to get within() to work.
But if that does not work, try computing.
Consider a horizontal line through the point. Find the points where it crosses the line segments of the sides. (Take care of the special case of a line segment being on your horizontal line.) Count the points to the left of your point. If it is odd, then the point is inside.
