 -O2 (ok with -O1 or gcc-3.3.6)

Please take me off the CC list for this distribution.

I don't need the "encouragement" of knowing that many people experience 
similar frustrations with gcc's poor (or shall I say, uninformative) 
warning messages in the case of aliasing rule violations.

Thanks,
Jonathan
