Looks like I'm currently using older arm-none-linux-gnueabi-gcc
(Sourcery CodeBench Lite 2014.05-29) 4.8.3 20140320 (prerelease).
I think the Debian compiler was not working few months ago and
I changed to something I had around.
Looks like the warning does not appear with arm-linux-gnueabihf-gcc
(Debian 6.1.1-3) 6.1.1 20160511.

Tony
