SGI symlink bug?

In the past two days, I have accidentally blown away two files
of mine due to (a) my inate dyslexia w.r.t the arguments to "ln -s",
and (b) a difference in behavior of "ln -s" on BSD machines -vs-
an SGI.
Here is a command sequence taken from a Gould PN 9080 running
UTX/2.0, a 4.2 BSD system:
15 spark> echo > foo
16 spark> ls -l foo
-rw-rw-r-- 1 mike 0 Jun 14 06:28 foo
17 spark> ln -s /tmp foo
foo: File exists
18 spark> ls -l foo
-rw-rw-r-- 1 mike 0 Jun 14 06:28 foo
19 spark>
Here is the same command sequence tried on an SGI Predator 4D/280
running IRIX 3.2.2:
1 wolf> echo > foo
2 wolf> ls -l foo
-rw-rw-r-- 1 mike graphics 0 Jun 14 06:28 foo
3 wolf> ln -s /tmp foo
4 wolf> ls -l foo
l--------- 1 mike graphics 4 Jun 14 06:28 foo -> /tmp
5 wolf>
If it would not be too much trouble, I'd like to ask the SGI
folks to duplicate the "foo: File exists" behavior, if it isn't
too hard.
Best,
-Mike
