You made your original assertion in response to Diez saying

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.
