+206: ":SB-FLUID feature broken"
+  (reported by Antonio Martinez-Shotton sbcl-devel 2002-10-07)
+  Enabling :SB-FLUID in the target-features list in sbcl-0.7.8 breaks
+  the build.
+
+207: "poorly distributed SXHASH results for compound data"
+  SBCL's SXHASH could probably try a little harder. ANSI: "the
+  intent is that an implementation should make a good-faith
+  effort to produce hash-codes that are well distributed
+  within the range of non-negative fixnums". But
+       (let ((hits (make-hash-table)))
+         (dotimes (i 16)
+           (dotimes (j 16)
+             (let* ((ij (cons i j))
+                     (newlist (push ij (gethash (sxhash ij) hits))))
+               (when (cdr newlist)
+                 (format t "~&collision: ~S~%" newlist))))))
+  reports lots of collisions in sbcl-0.7.8. A stronger MIX function
+  would be an obvious way of fix. Maybe it would be acceptably efficient
+  to redo MIX using a lookup into a 256-entry s-box containing
+  29-bit pseudorandom numbers?
+
+208: "package confusion in PCL handling of structure slot handlers"
+  In sbcl-0.7.8 compiling and loading 
+       (in-package :cl)
+       (defstruct foo (slot (error "missing")) :type list :read-only t)
+       (defmethod print-object ((foo foo) stream) (print nil stream))
+  causes CERROR "attempting to modify a symbol in the COMMON-LISP
+  package: FOO-SLOT". (This is fairly bad code, but still it's hard
+  to see that it should cause symbols to be interned in the CL package.)
+
+209: "DOCUMENTATION generic function has wrong argument precedence order"
+  The method from 
+    (DEFMETHOD DOCUMENTATION ((X (EQL '+)) Y) "WRONG!")
+  should not be executed in the call 
+    (DOCUMENTATION '+ 'FUNCTION),
+  as the DOCUMENTATION generic function has a different argument
+  precedence order (see its entry in the CLHS). However, despite a
+  correct generic function definition in the PCL source code, SBCL
+  returns "WRONG!" for the call.
