I guess I don't see the advantage of that approach (except perhaps for
simplicity), compared to using the registry to store path information
and then using environmental variables to set it when needed. It would
be nice if Rtools didn't override existing windows executables, in the
same way it would be nice if windows worked like linux out of the box.
But since it doesn't, and since in general adding more and more
directories to the path makes it more and more likely for some
conflict to arise, I think Rtools current approach is very reasonable.
