When trying to compile anything that uses the cmdlib.c file it comes up with this error. I was able to comment out the line and it would work, but since I wasn't sure what exactly this does I figured that shouldn't be the way to go. I would define it if I knew what to define it as, but there are others that I'm sure know what it should be.
