Thanks Charles.  I agree completely and will add that they will pry Ken's compilers, so wonderfully supported by you, from my cold, dead fingers.  South Suite's new kernel will always be compiled with 6c.  As far as performance goes, to paraphrase Chuck Yeager, it's not the compiler, it's the coder.  I'd rather have brilliant coders than idiot savant compilers.
