Interesting, what does "uname -a" report on your machine?

I agree that darwin-x86_64 is no longer a legal target architecture, we 
removed that in R3.14.11 when we put in the ARCH_CLASS setting, but I 
obviously missed the startup host architecture tests.  I don't think we can 
cope with someone doing strange things to ARCH_CLASS, but 

I don't have access to any Macs here that are configured to be 64-bit by 
default, and I'm not sure if it's possible to switch a machine to 64-bit 
without rebooting anyway.  If anyone knows how I can run an ssh session in 64-
bit on an otherwise 32-bit Mac, please elucidate!
