** OPEN and WITH-OPEN-STREAM allow opening streams with
element-type larger than ([UN]SIGNED-BYTE 32).
+changes in sbcl-0.8.9 relative to sbcl-0.8.8:
+ * deprecation of old extension: *DEBUG-PRINT-LEVEL* and
+ *DEBUG-PRINT-LENGTH* are now deprecated in favor of the new, more
+ general SB-DEBUG:*DEBUG-PRINT-VARIABLE-ALIST* mechanism. (This
+ should matter to you only if you rebind the printer control
+ variables and then find you want different bindings in the
+ debugger than in the ordinary execution of your program.)
+ * The runtime build system has been tweaked to support building
+ (on SPARC/SunOS) using a C compiler which invokes Sun's own
+ assembler and linker. (thanks to Nikodemus Siivola)
+ * Unbound, undefined, undeclared variables now trigger full
+ WARNINGs, not just STYLE-WARNINGs, on the assumption that this is
+ more often programmer error than deliberate exploitation of undefined
+ behaviour.
+ * optimization: implemented multiplication as a modular
+ (UNSIGNED-BYTE 32) operation on the PPC backend.
+ * fixed some bugs revealed by Paul Dietz' test suite:
+ ** ADJUST-ARRAY now copies the datum in a zero rank array if
+ required.
+ ** ADJUST-ARRAY no longer adjusts non-adjustable arrays.
+ ** MAKE-STRING-INPUT-STREAM accepts NIL as a value for :END.
+ ** MAKE-STRING-INPUT-STREAM functions correctly for strings with
+ element-type NIL.
+ ** CLEAR-INPUT accepts NIL and T for its (optional) stream
+ argument.
+ ** Ratios can now be printed correctly with *PRINT-BASE* bound to
+ 2, 8 or 16.
+ ** ECHO-STREAMs no longer attempt to echo the end of file value to
+ their output stream on EOF from read.
+ ** CONCATENATED-STREAM-STREAMS discards constituent streams which
+ have been read to end-of-file.
+ ** CLOSE works as expected on the null CONCATENATED-STREAM, and on
+ STRING-STREAMS.
+ ** Printing symbols with *PRINT-CASE* :CAPITALIZE respects the
+ description of determination of which consecutive characters
+ constitute a word.
+ ** Printing the "Space" character with escaping on now yields "#\\ ",
+ rather than "#\\Space", as mandated by ANSI 22.1.3.2.

planned incompatible changes in 0.8.x:
* (not done yet, but planned:) When the profiling interface settles
down, it might impact TRACE. They both encapsulate functions, and
