[cvs-nhc98] Bugfix for strict datatypes in the (old) tracing transform

malcolm: Tue Nov 13 15:18:15 CET 2001 Update of /usr/src/master/nhc/src/compiler98 In directory hinken:/tmp/cvs-serv19549 Modified Files: DbgDataTrans.hs Log Message: Bugfix for strict datatypes in the (old) tracing transformation. Previously, a type like data AB a = C !a !a was transformed to data AB a = C (R !a) (R !a) This type is incorrect, but appeared in interface files nevertheless, whence it could not be parsed back in. This fix makes the transformation produce the type data AB a = C !(R a) !(R a) which is also somewhat incorrect (or misleading) but is actually parsable.
