What is the case with Claws Mail? Would the build
benefit or suffer from using "-O3" instead of "-O2"?
Also: I would like to use a faster machine to create
builds for other slower machines (one of them even
32-bit). Do I need anything more than just finding the
proper "-march" setting for the target CPU?
