Let me guess--you come from a Linux background, right?

Yes. The developers go to great pains to ensure a stable platform. 
What, you think Theo's never heard of compile options? Or that he and 
the rest of the gang have some twisted desire that you run a slow 
system while they chuckle evilly in their dungeons on their uber-fast 
systems compiled with all the secret hacks?

On the other hand, if you're looking to experiment, to learn the 
effects of compiler optimization, perhaps even to fix what breaks--by 
all means, experiment! Take it apart, put it back together again in 
different ways, and have fun. Of course, you'll also need to understand 
the code and the compiler, which is no small task.

But you'd be nuts to do so for anything other than a learning 
environment....
