It's a bit of an oversimplification to call Mac OS X' kernel "FreeBSD- 
based". See here for some background: http://books.google.com/books?id=K8vUkpOXhN4C&pg=PA48 
  (under "2.4 The xnu kernel"). But that's irrelevant, since FPC for  
Mac OS X does not use any direct kernel interface, due to the kernel  
interface not being supported for application development (in practice  
this means that the system call interface can change even between  
minor OS patches, if deemed useful for whatever reason).

On Mac OS X, we use libc, and that interface is indeed pretty much  
100% compatible between the desktop and iPhone versions of Mac OS X.
