-Oz does not optimze loop like remove calc from loop that can done outside
and other nice stuff.. it feal -Oz is slower that -O3. I use -O3 in DBG=1
and standard setting for DBG=0 it feal that release build being slower that
DBG=1 with -O3. The O3 slight produst lite biger exe files. but alot better
optimze for speed that -Oz.
