> I tried the 'ln -s' command in bothe 4.3 & 4.7 in a situation where it should fail and it did, but it still had a return/exit code of 0 , I think it should have been nonzero. I tried 'ln -s a b' where the file b existed (and was a directory) and I wanted to create the file named a also pointing to it. The correct form was 'ln -s b a'.

Hmm... I just tried this and I didn't see this behavior on 4.7-R:
-bash-2.05b$ ln -s a z
ln: z: File exists
-bash-2.05b$ echo $?
1
-bash-2.05b$ ln -s z a
-bash-2.05b$ echo $?
0
-bash-2.05b$ uname -a

Looks like the EEXIST is returning non-zero...
