I am sure it as already been answered, or possibly you have done some research in the time you have posted - but the 70-200 is not a macro lens. At its closest focus distance, at maximum focal length, it will not magnify the subject any more than 1:4 if I am not mistaken..
If you are really talking about macro photography the choice is obvious, the 100m macro, if however you are simply wanting close shots of things (dragon flys, reptiles, birds, etc) and are wanting to fill the frame with them as close as you can typically get to them then the 70-200mm will give you a lens with greater diversity, not to mention greater focal length options.
As was mentioned above if you are willing to sacrifice the focus range (no infinity focus) you can stack extension tubes to bring the minimum focus distance of the 70-200 to around 10inches - but a maximum focal distance of less than ~8feet. With the extension tubes you would be hard pressed to see any optical quality differences, it is a very sharp lens at native focus ranges, shorten that range so you are physically closer to the subject and you have a very useful 'close focus' zoom. You will also lose light stacking the extension tubes, but you typically stop down macro anyway, it will darken the viewfinder a little though. Curvature of the focal plane with the 70-200mm (soft corners) will not be all that relevant in the field, and you will probably not notice at all on a cropped sensor like the 60D. If your shooting flat objects like stamps or coins, and will be scrutinizing the corners of the frame, you may want to get the true macro lens.
