From a plain-old-user's point of view, I'd much rather see Roger's 
original version. I don't want to rely on undocumented autoconf 
internals any more than I have to. As soon as you release a version of 
autoconf with this macro set included and people start relying on these 
internal variables, you've just committed to never changing them in the 
future.
