Oops, obviously the last line should be:

    cat <directory>/link

or:

    cat $HERE/link

Huh? I just backed out all the changes I made, did a CVS update and rebuilt
fileutils, sh-utils and textutils, then tried this:

bash-2.04$ cd /temp/
bash-2.04$ mkdir -p somewhere/over/the/rainbow
bash-2.04$ cd somewhere/over/the/rainbow/
bash-2.04$ pwd
c:/temp/somewhere/over/the/rainbow
bash-2.04$ HERE=`pwd`
bash-2.04$ ln -s /dev/env/FOO link
bash-2.04$ export FOO=../../somefile
bash-2.04$ echo Hello > $FOO
bash-2.04$ ls -l $FOO
-rw-r--r--    1 rich     root            7 Jan 18 11:55 ../../somefile
bash-2.04$ cat link
Hello
bash-2.04$ cd ..
bash-2.04$ cat rainbow/link
c:/djgpp.204/bin/cat.exe: rainbow/link: No such file or directory (ENOENT)
bash-2.04$ ls -l rainbow/link
lrw-r--r--    1 rich     root          510 Jan 18 11:55 rainbow/link ->
/dev/env/FOO
bash-2.04$ cat $HERE/link
c:/djgpp.204/bin/cat.exe: c:/temp/somewhere/over/the/rainbow/link: No such
file
or directory (ENOENT)
bash-2.04$ ls -l $HERE/link
lrw-r--r--    1 rich     root          510 Jan 18 11:55
c:/temp/somewhere/over/the/rainbow/link -> /dev/env/FOO

ls -l shows the link "link" as satisfied, when I am in $HERE, but broken, when
I am in "$HERE/..".

Bye, Rich =]
