Yes, which does *NOT* include defining Pi and other such questionable 
things. Those things are for darwin compatibility, not cocoa, and I've 
yet to run across a cocoa app that needed them when I was porting stuff. 
So I've got loads of anecdotal evidence that it's not necessary. I think 
the potential for it to cause problems is greater than the potential 
benefit for the one or two apps that might need these #defines.

As I said, I've yet to come across an OS X app which I was porting which 
needed any of these extras. Since the number of apps that need these 
extra things is low, they either be in a separate header file or removed 
completely.

I respectfully disagree. You are operating under the assumption that 
these defines are necessary to port apps, when nothing could be further 
from the truth 99% of the time. As I said earlier, the potential 
downsides (which I outlined above) outweigh any miniscule benefits which 
may exist.
