gEDA-user: ps.c alignment lines multiplies by zero?

[Bob Paddock <bob.paddock@xxxxxxxxx>]

Can anyone offer me some insight to why this code
is doing a multiplication by zero?  Was thick originally
meant be be something that could be passed in
to control the thickness of the alignment lines?

Note the thick*2:

static void
corner (int x, int y, int dx, int dy)
{
#if 0
  int len = (PCB->MaxWidth + PCB->MaxHeight) / 10;
  int len2 = (PCB->MaxWidth + PCB->MaxHeight) / 50;
#else
  int len = 200000;
  int len2 = 20000;
#endif
  int thick = 0;

  fprintf (f, "gsave %d setlinewidth %d %d translate %d %d scale\n",
	   thick * 2, x, y, dx, dy);
  fprintf (f, "%d %d moveto %d %d %d 0 90 arc %d %d lineto\n",
	   len, thick, thick, thick, len2 + thick, thick, len);
  if (dx < 0 && dy < 0)
    fprintf (f, "%d %d moveto 0 %d rlineto\n",
	     len2 * 2 + thick, thick, -len2);
  fprintf (f, "stroke grestore\n");
}
