Seriously? gEDA can't draw circles? I think the first thing before this discussion gets out of hand is to asap add clicking x/y to set center and clicking again to set radius or just popping up a dialogbox to set radius/correct XY after one click in 'circle' tool mode.
Then you can spend the next 5 years arguing how to implement arc editing.
