[cvs-nhc98] patch applied (hat): Hat-trans: added / improved error messages for faulty input module.

Tue Jun 11 03:41:21 PDT 2002 olaf * Hat-trans: added / improved error messages for faulty input module. This also removes the following bug: 3. hat-trans suffers a pattern-match failure if the source program has an empty import list Actually the pattern-match failure had nothing to do with an empty import list. It occurred when a data constructor that was not in scope occurred in a pattern.
