PCB doesn't support non-circular holes. What I usually do is defining a 
layer (or just use the outline layer) and set up a style with a line width 
matching the diameter of the drill bit then draw the path. PCB will take 
this as a copper layer (with some side effects if it's called outline), 
but at the end these "traces" are easy to use for milling. At least this 
was my experience with gerber and a fab house.
