 Changes to the Mercury compiler:
+
+* There's a new warning option `--warn-dead-procs' which can be used
+  for detecting unreachable code.
+
+  This is not yet enabled by default, because it can cause some spurious
+  warnings in modules containing code which mixes Mercury clauses and
+  `pragma foreign_proc' declarations for the same procedure.
 
 * `mmc --make' now works correctly with Microsoft Visual C++.
