But your C++ program outputs times in seconds, right? So all
compilations except for the first two give results in less than a
second, right? (meaning the optimizations of your standard-compilation
give worst results than -O3?)

BTW, I don't quite understand your gcc optimizations for the first 2
compiles anyways: two -O options with different values. Doesn't that
mean the 2nd -O takes preference, and the compilation is at -O2 instead
of -O3?

Why both -O3 and -O2 at the command-line?
