Ok, scratch that thing about options being out-of-date. I didn't realize (until rereading the docs a little
more closely and then verifying in the sources) that "-Os" turns on optimizations that aren't available
via any fine-grained "-f" option. (Maybe that should be changed? Why not have "-foptimize-size"?)
