It is a FAQ that you can't get the effects of -Oy with -Ox and a bunch
of -f flags. Some things depend directly on the optimization level.
For example, inlining of free functions. By the way, I think it is a
*very* common experience that -O3 doesn't do better than -O2. Thus I'm
not particularly surprised or worried ;)
