I don't think such merging makes a lot of sense.
Most of the C APIs used in the Mac port (e.g., Core Foundation, Core
Graphics, Core Text, and Grand Central Dispatch) are available and
widely used on iOS as well as Mac OS X. (Ironically, major difference
between them lies in UIKit vs. AppKit, being C APIs mentioned above
almost identical.) If GNUstep incorporates these "Core" C APIs (IIUC,
it is going to that direction more or less), then many part of the Mac
port can be reused. This doesn't require any knowledge of Emacs
internals, and moreover benefits outside Emacs.
