As I read it, the code only consists of darwin bits...  If I'm wrong,  
the below only applies to the darwin only bits.

Ok, but one thing to think about....

You meant to do this, as some other code does what needs doing for  
x86_64, right?  This is mainly a rhetorical question as I suspect the  
answer is yes, but I have to ask anyway.

I'll try and build and fix any darwin9 building problems after you  
check it in.  Since it is 4.2 we're talking about, please try and  
watch for any fallout from this...

Thanks
