+changes relative to sbcl-1.0.53:
+ * minor incompatible changes:
+ ** RENAME-FILE on a symbolic links used to rename the linked-to file instead
+ of the link.
+ ** DELETE-DIRECTORY on symbolic link to a directory used to delete the
+ directory, but now signal an error instead. Use TRUENAME to resolve
+ the pathname if you wish to delete the linked directory, and DELETE-FILE
+ if you wish to delete the
+ * enchancement: on CHENEYGC targets, SB-KERNEL:MAKE-LISP-OBJ now does
+ the same validation of pointer objects as GENCGC does, instead of a
+ comparatively weak bounds-check against the heap spaces.
+ * enhancement: on win32, ABS of complex floats guards better against
+ overflows. (lp#888410)
+ * bug fix: on 64-bit targets, atomic-incf/aref does index computation
+ correctly, even on wide-fixnum builds. (lp#887220)
+ * bug fix: (directory "foo/*/*.*") did not follow symlinks in foo/ that
+ resolved to directories.
+ * bug fix: SB-KERNEL:MAKE-LISP-OBJ on GENCGC no longer categorically
+ refuses to create SIMPLE-FUN objects.
+ * bug fix: type mismatch when assigning to lexical variables no longer
+ result in fasl-dumping internal type objects. (lp#890750)
+ * bug fix: type mismatch on (setf aref) and function return values no
+ longer result in fasl-dumping internal type objects.
+ * bug fix: SB-BSD-SOCKETS:GET-PROTOCOL-BY-NAME leaked foreign memory.
