get them into compiler string, but can't remember how!

This would then only work plausably if the function which uses that
optimization to string functionality is defined inside the main program as
each unit can be compiled differently. Also -O2, etc. are not the only
optimization parameters: every specific optimization can be switched on and
off independently of the optimization level and then there's also the
"whole program optimization". So you see that this is not trivial.
