True only if there is a "foo'' subdirectory within a directory in CDPATH.
If "." isn't included in CDPATH cd acts as if "." were the last entry.

Apparently it's better to just undefine CDPATH when compiling just to be on 
the safe side:

http://mail.gnu.org/pipermail/bug-libtool/1998-May/000933.html
http://sources.redhat.com/ml/bug-automake/1999/msg00124.html
http://www.mail-archive.com/bug-fileutils AT gnu DOT org/msg00807.html

   (bash) $ export CDPATH=.:$HOME
   (bash) $ cd /tmp
   (bash) $ mkdir foo
   (bash) $ here=`cd foo && pwd`
   (bash) $ echo $here

This will cause bash to print the directory name twice. If CDPATH is set, 
bash echoes the directory name.
