Ah, I thought special_function_p would strip off __builtin_ prefix from tname,
but apparently it doesn't.  I'd say it should, something like:

--- gcc/calls.c2009-01-28 12:57:50.000000000 +0100
+++ gcc/calls.c2009-01-30 18:22:26.000000000 +0100
@@ -498,10 +498,14 @@ special_function_p (const_tree fndecl, i
        && ! strcmp (name, "__builtin_alloca"))))
 flags |= ECF_MAY_BE_ALLOCA;

-      /* Disregard prefix _, __ or __x.  */
+      /* Disregard prefix _, __, __x or __builtin_.  */
       if (name[0] == '_')
 {
-  if (name[1] == '_' && name[2] == 'x')
+  if (name[1] == '_'
+      && name[2] == 'b'
+      && !strncmp (name + 3, "uiltin_", 7))
+    tname += 10;
+  else if (name[1] == '_' && name[2] == 'x')
     tname += 3;
   else if (name[1] == '_')
     tname += 2;
