Question: Can I build a simple "hello world" text/console mode binary in Darwin, and would that binary then work unmodified on the corresponding (see table in article) MacOS release? According to the article, you don't get a lot of features that you get with MacOS, with Darwin, e.g., GUI, etc. That's OK. But, what I want to know is, if I write a console program without using any of those features (GUI, etc.) on Darwin, then could it work on the corresponding MacOS, unmodified? Why or why not?
