Hi Paul,
  I haven't built the trunk for a few months, but nothing here seems to have
changed.  You could try changing line 91 from:

     nsIID *iid_ret;
to:
     const nsIID *iid_ret;

as that is how other users of that interface appear to declare their
variable.  I've no idea why compilers on other platforms don't also
complain, but whatever... :)

Mark
