[cvs-nhc98] Add the correct aux information to fieldnames in datatype

malcolm: Fri Dec 20 17:26:08 CET 2002 Update of /usr/src/master/nhc/src/hat/trans In directory hinken:/tmp/cvs-serv23875 Modified Files: AuxLabelAST.hs Log Message: Add the correct aux information to fieldnames in datatype declarations during the syntax-tree re-labelling phase. Previously, we treated fieldnames as lambda-bound variables, but they are really let-bound. This additionally meant that the wrong arity was appearing for fieldnames in the info tables generated by hat-trans.
