Good point.  Would "generic i686" be a reasonable choice?  Does that even 
mean anything these days?

Anyway-- I'd appreciate some guidance on what you folks would find most 
interesting and useful.  Then I can do some homework and figure out how to 
get the rest of the compilers to assume an equivalent ISA.
