Nope. I don't have alpha/pc98/sparc/ia64 bits in my x86 tree. I don't
have any need for them, so why have them fill up my tree. On my alpha,
I don't have the non-relevant bits as well.
In short, unless you *define* a standard ahead of time, you can't
guarantee a consistent answer.
And, it still takes *way* too long to calculate.
