But I had a fruitful discussion with the PowerPC people, who went through (and are still completing) the transition to one directory. Their verdict, surprisingly, was definitely positive. They started with a single powerpc dir which simply included ppc64/ or ppc/, then pulled parts into that directory until ppc64/ was gone. The things left in ppc/ are being slowly merged, and some may be dropped entirely. They can obviously speak for themselves, but the cleanup caused by the movement was seen as a net win. Rusty.
