+  if (warn_cast_incomplete)
+    if (!COMPLETE_TYPE_P (TREE_TYPE (type))  ||  !COMPLETE_TYPE_P (TREE_TYPE (otype)))
+      warning ("casting from/to an incomplete type is risky; see -Wno-cast-incomplete");
+

Lines must not be longer than 78 characters. Also leave out the "see",
we don't do that for any other warning.

+class Beta;        *b;   // Incomplete class

Spurious ;.

The changelog lacks file references. Also, you need test cases
(http://gcc.gnu.org/codingconventions.html).  If you have that, I
suggest you post your patch to gcc-patches.
