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.
