Yes, bitrot. I don't see a rearrangement of system headers happening in 2.4.

I question that. Athlon does branch prediction on call targets, function
calls are cheap. 3dnow saves 25%-50% of cycles on a copy. How many function
calls can be paid for with 1000 cycles or so?
My patch still inlines the standard string const_memcpy for the case of
small known length.
If I configure SMP for a UP box, performance is clearly not my first
concern. If I have a real SMP Athlon system, performance should not improve
by only using one processor.
How about we get it to build before we optimize it?
