It is controllable separately with a compiler switch. The -release switch is just a combination of the most popular options for a release build. The point of having it is that it reduces the need for long lists of switches common for doing a release build in C++. Also, I find many people new to a compiler find it frustrating to have to decipher complex lists of switches just to figure out how to get an optimized, release build.
