And what about trying this:

	return vgl_distance2_to_linesegment(float(x0), float(y0), x1, y1, x, y);

Peter,

I just committed the more portable fix we discussed, below.  -Fred

float vgui_soview2D_lineseg::distance_squared(float x, float y) const
{
  // Here we explicitely cast some parameters to type float to help
  // the Borland compiler, which otherwise tries to use
  // vgl_distance2_to_linesegment<const float>, presumably because
  // this is a const member function so some of the parameters passed
  // to vgl_distance2_to_linesegment are effectively of type const
  // float.
  return vgl_distance2_to_linesegment(float(x0), float(y0), float(x1),
float(y1), x, y);
}
