No, it isn't. -O<number> parameters will _enable_ certain optimizations.
This means, -O3 -O1 will not switch the compiler "back" to -O1, just stay
at -O3, because at -O3 level, all -O1 optimizations are already enabled,
there is nothing to enable.
-O- however will disable all optimizations. So if you want to disable all
previously enabled optimizations, you indeed need to go to the -O- -O1
route. So it is actually useful.
(The above is quite easy to verify, see options.pas, line 2350 and below
in the compiler sources.)

Good to know.
Now I am pretty sure that I copy that options from someone else, because
with my knowledge I could not figure out that myself.
Thank you Charlie.
Best Regards.
