Looking at some autoconf-generated configure script I've found the following:

# The HP-UX ksh and POSIX shell print the target directory to stdout
# if CDPATH is set.
(unset CDPATH) >/dev/null 2>&1 && unset CDPATH

I had once stumbled over this problem and ever since I keep using

cd bla > /dev/null

whenever the output could possibly trouble me. But well, actually, unsetting
CDPATH would be more appropriate.
