+-- remove obsolete (Lin C) expressions before doing anything else. AR 21/6/2003
+--
+-- What the program does is replace the occurrences of Lin C with the actual
+-- definition T given in lincat C = T ; with {s : Str} if no lincat is found.
+-- The procedure is uncertain, if T contains another Lin.
