Optimizing for size (-Os) is mainly benneficial for embedded systems and systems with very small CPU caches (correct me if I'm wrong). So it seems wrong to me that CC_OPTIMIZE_FOR_SIZE defaults to 'y' and recommends saying 'Y' if unsure. I believe it should default to 'n' and recommend that if unsure. People who bennefit from -Os know who they are and can enable the option if needed/wanted - the majority shouldn't select this. Right?
