The Oolite game (https://github.com/OoliteProject/oolite) was originally
developed on Mac but now only works on Windows and Linux using GNUstep due to
the Mac architecture change a few years ago. What would be the best approach to
port the application to modern Mac (with regard to the Objective-C/GNUstep
part)? For example, is it best to try to use the Mac APIs directly or to
compile GNUstep Base for Mac if that's possible? Are there any gotchas or
blockers to look out for? Are there any examples of projects using GNUstep that
work on modern Mac as well as Windows and/or Linux?
