+    * better position info with UseTokenInfo
+      UseTokenInfo greatly simplified
+    + added check for changed tree after first time firstpass
+      (if we could remove all the cases were it happen
+      we could skip all firstpass if firstpasscount > 1)
+      Only with ExtDebug
+
+  Revision 1.5  1998/04/30 15:59:43  pierre
     * GDB works again better :
       correct type info in one pass
     + UseTokenInfo for better source position
