You made your original assertion in response to Diez saying >>And this presumes an architecture which byte-addresses and only >> uses "aligned" addresses. He was talking about the arachiteecture, for Pete's sake, not a compiler. I personally find it irritating that you continue to try and justify your assertions even when you are plainly on shaky ground, which tends to make the threads you are involved in endless. Sorry for the ad hominem remarks, which I normally try and avoid, but this (ab)uses newsgroup bandwidth unnecessarily. Unwillingness to admit any mistake can be rather unattractive. Can't you, just once, say "I was wrong"? Or are you perchance related to President Bush? Better still, just let these small things go without further comment. regards Steve -- Steve Holden +44 150 684 7255 +1 800 494 3119 Holden Web LLC www.holdenweb.com PyCon TX 2006 www.python.org/pycon/ -- http://mail.python.org/mailman/listinfo/python-list
