I got caught out on this myself, so I downloaded a gerber spec from the web somewhere. Specifically, the line means:
%AD Aperture description D34 Name of the aperture P, It's a regular polygon 0.063X Size of the polygon 8X It's has 8 sides 0 NOT rotated *% End of description The printout I have suggests that for no rotation, do not use the rotation parameter. IMHO it sounds like the manufacturer's interpretation of the gerber data is not correct.
