I'm sure Thomas will come screaming when he sees this :)

I don't use it myself, but because of gcc's stupidity, it does not 
detect uninitialized variables unless you optimize. What this means is 
that we're all merrily working on DBG = 1, and when it's release time, 
optimizations are turned on and everything breaks because uninitialized 
variables are detected. Plus, it's actually a good thing to find them, 
because it makes finding bugs easier. So OPTIMIZED was created to allow 
-Os to be used even if it's a debug build, so that such errors can be 
detected.

So it's actually a source of eliminiating build errors. But, personally, 
I don't use it, and only Thomas begged me for it...
