I successfully built and uploaded this version of arts on an arm machine. The quoted warnings don't cause the failure, the actual failing line is the link line, which is >/dev/null 2>&1 so we don't see whatever the build error was. (/dev/nulling errors during compiles considered self-defeating.)
Anyway, I can't reproduce it, so unless it happens on a future build on the buildd, I don't think it's RC. -- see shy jo
