Why did you need this change? Are you seeing a redefinition warning? If so, what command are you using to run the Posix simulator?

Some old gcc version complain with redefined warning. The second one with every gcc version and -Wundef: GCC/Posix/port.c:308:9: warning: "APPLE" is not defined, evaluates to 0 [-Wundef]

How did you verify your change? I'm assuming you must have ran the Posix simulator to have seen these issues. |
Yes, I started to use the posix simulator in my projects several years ago, it works fine. |
