+       bootstrap: don't let a user's CDPATH setting affect this script
+       When CDPATH is set, cd will sometimes generate output.
+       When "cd" is run in a subshell whose output matters, that
+       surprising-to-some output can cause malfunction.
+       Unsetting CDPATH turns off this shell "feature."
+       * build-aux/bootstrap (CDPATH): Unset.
