+changes in sbcl-0.8.6 relative to sbcl-0.8.5:
+ * fixed a bootstrapping bug: the build process no longer assumes
+ that the various BOOLE-related constants have the same value in
+ host and target lisps. (noted by Paul Dietz' test suite on an
+ SBCL binary built from CLISP)
+ * the system can now be dynamically linked on the MIPS platform,
+ which enables dynamic loading of foreign code from Lisp. (thanks
+ to Ralf Baechle for discussions on the MIPS ABI)
+ * the system now records its own debugging information in a
+ filesystem-position-independent manner, relative to the "SYS"
+ logical host.
+ * fixed a compiler bug: MV-LET convertion did not check references
+ to the "max args" entry point. (reported by Brian Downing)
+ * tweaked disassembly notes to be less confident about proclaiming
+ some instruction as an LRA. (thanks to Brian Downing)
+ * contrib update: SB-ACLREPL is now threadsafe; multiple listeners
+ now each have their own history, command character, and other
+ characteristics. (thanks to David Lichteblau)
+ * fixed some bugs revealed by Paul Dietz' test suite:
+ ** compiler failure in compiling LOGAND expressions including a
+ constant 0.
+ ** implementation of ASH-MOD32 on X86 and PPC did not work for the
+ shift greater than 32.
+ ** FLUSH-DEST did not mark blocks for type check regeneration.
+ ** HANDLER-CASE failed to accept declarations in handler clauses
+ in some circumstances.
