   On #2, if there are any likely-looking message files, it's possible that   
   SET MESSAGE with the right one might get the condition value   
   translatable to a meaningful message.   
      
   On #1, remember that the value of errno doesn't mean anything except   
   immediately after the error, so if C is successful but Pascal is not,   
   the fact that you get different errno values doesn't really tell you   
   anything.  If there is an error from both languages, then it does sound   
   like something is different about the initialization of the image or the   
   debugger session.  Since the debugger does have language-specific   
   features, it may be a more likely suspect.
