+changes in sbcl-0.9.8 relative to sbcl-0.9.7:
+ * fixed bug #390: :CHARACTER-SET pathname components now work as
+ expected. (reported by Tim Daly Jr)
+ * fixed bug #391: complicated :TYPE intersections in slot
+ definitions no longer cause an error in PCL internals.
+ * fixed bug #392: plugged a hole in the obsolete-instance protocol.
+ * bug fix: FILE-STRING-LENGTH is now external-format sensitive,
+ returning the number of octets which would be written to the
+ file-stream. (thanks to Robert J. Macomber)
+ * bug fix: the SB-SIMPLE-STREAMS contrib passes external-format
+ arguments to the internal stream functions. (thanks to David
+ Lichteblau)
+ * optimization: improved type inference for arithmetic-for
+ index variables in LOOP
+ * optimization: faster floating-point SQRT on x86-64
+ * fixed some bugs revealed by Paul Dietz' test suite:
+ ** DOCUMENTATION returns NIL instead of "" for method combinations
+ that don't have a docstring
