I think we in PPC land have gotten used to that "style" because we have
one kernel that supports different "platforms", i.e. it selects the
appropriate code at runtime as George says. In general that's a little
bit slower and a little bit bigger.
Unless you need to choose among PPC KGDB functions at runtime, which I
don't think you do, you don't need it...
