This has come up previously -- configure and probably most
of our other shell scripts will also break in the presence
of CDPATH. I stand by my position that CDPATH is a bad
misfeature that the shell should not be applying to
scripts. If anybody ever reports a bug we could I suppose
unconditionally unset CDPATH at the top of all our scripts.
