If you want to figure out what that code is doing and rewrite it to be 
compliant with strict aliasing, go ahead (I tried, and it made my brain 
hurt).  In the meantime, we shouldn't be enabling the optimization on 
code that was written for an older version of the C language where such 
an optimization was prohibited, and where the compiler is letting us 
know that it thinks the code depends on the older semantics.
