Very interested in leveraging XPC for some work. I'm particularly interested in controlling AI aircraft. It seems that the features added this past summer (on develop branch) enabling pausing the simulation for AI aircraft is not included in the Mac binary (mac.xpl).

For example, passing 101 pauseSim results in:

[12:48:54] TRACE|DBUG| 53 49 4d 55 00 65
[12:48:54] DEBUG|DBUG|Head: SIMU Size: 6 101
[12:48:54] TRACE|SIMU|Message Received (Conn 0)
[12:48:54] ERROR|SIMU|ERROR: Invalid argument: 101

The code looks right in MessageHandlers.cpp on Develop. Trying to build the Xcode project (Xcode 9.3) throws an error:

...XPCPlugin.cpp:97:7: Call to 'abs' is ambiguous

Any advice/help in getting the develop branch working on Mac would be great. Thanks!
