>Description:
When setting the $CDPATH environment variable, `cd' in shell scripts
doesn't do what it should every time.  I noticed this when running
build.sh from /usr/src via ./build.sh.  With a set $CDPATH it complains
not to be run from /usr/src because it does a "cd `dirname $0`", i.e. it
executes "cd ." and gets to the first directory in $CDPATH.

#v+
aw@schroeder:~> cat test.sh
#!/bin/sh

echo CDPATH=$CDPATH
pwd
cd .
pwd
aw@schroeder:~> ./test.sh
CDPATH=
/home/aw
/home/aw
aw@schroeder:~> export CDPATH=/tmp
aw@schroeder:~> ./test.sh
CDPATH=/tmp
/home/aw
/tmp
aw@schroeder:~>
#v-

With "#!/bin/ksh" or "#!/usr/pkg/bin/zsh" this doesn't happen.

>How-To-Repeat:
See above.
