Depends on your definition of optimized.  Smaller binaries do not
necessarily run faster.  They may for example, have less inlining and
so higher procedure call overheads.

Also, if you are simply looking at the size of the resulting binary
file on disc, don't.  You should look at the output of the size
command instead.  Some compilers may put more debug stuff into the
binary in places where the loader may not necessarily load it into
RAM.  Particularly if -g is still present in the compiler options
list.
