I suspected so :( That's life anyway...

By studding my measurements I suspect that binary_search is automatically inlined in -O3 (probably
 because it is small). Anyway the "big fish" is lower_bound, binary_search is just more convenient
sometimes.

I found nothing appropriate in the manual. (-finline-limit works for functions that are explicitly
marked as inline)

Thank you very much,
