Well, I have XP SP1, and, as you saw, it worked.  Since I didn't *really*
try it with 1.5.11, but rather with a self-built DLL from CVS, you might
try the latest snapshot and see if that fixes your problem.  Otherwise, I
had a WAG that it had to do with the presence of .exe in the symlink name
and contents, but the guess didn't pan out for me -- it worked in all 4
combinations.

I don't believe you ever said whether the *exact* sequence of commands
below worked for you or not.

Ah, another possibly relevant point: I use perl 5.8.2-1...  Could you
please try that?
