+changes relative to sbcl-1.0.30:
+  * improvement: stack allocation is should now be possible in all nested
+    inlining cases: failure to stack allocate when equivalent code is manually
+    open coded is now considered a bug.
+  * new feature: experimental :EMIT-CFASL parameter to COMPILE-FILE can
+    be used to output toplevel compile-time effects into a separate .CFASL
+    file.
+  * optimization: multiplication and division of single- and double-floats
+    with constant +/-one has been optimized.
+  * optimization: multiplication of single- and double-floats floats by
+    constant two has been optimized.
+  * bug fix: moderately complex combinations of inline expansions could
+    be miscompiled if the result was declared to be dynamic extent.
+  * bug fix: in some cases no compiler note about failure to stack allocate
+    was emitted, even if the objects were in fact heap allocated.
+  * bug fix: minor violation of "otherwise inaccessible" rule for stack
+    allocation could cause objects users might reasonably expect to
+    be heap allocated to be stack allocated.
+  * bug fix: DESCRIBE signalled an error for generic functions under
+    certain circumstances. (reported by Leslie Polzer)

   * minor incompatible change: SB-THREAD:JOIN-THREAD-ERROR-THREAD and

     of SB-THREAD:THREAD-ERROR-THREAD.

   * optimization: the compiler now derives simple types for LOAD-VALUE-FORMs.
   * improvement: less unsafe constant folding in floating point arithmetic,
