changes in sbcl-0.8.2 relative to sbcl-0.8.1:

  * fixed bug 148: failure to inline-expand a local function left
    garbage, confusing the compiler.
  * fixed bugs 3cd: structure slot readers perform type check if the
    slot can have an invalid value (i.e. it is either not initialized
    or can be written with a less specific slot writer).
  * bug fix: the compiler now traps array references to elements off
    the end of an array; previously, the bounds checking in some
    circumstances could go off-by-one.
  * improved MACHINE-VERSION, especially on Linux (thanks to Lars
    Brinkhoff)
  * type declarations for array element types now obey the description
    on the CLHS page "Declaration TYPE", as per discussions on
    sbcl-help around 2003-05-08.  This means that a declaration
    (TYPE (ARRAY FOO) BAR) means that, within the scope of the
    declaration, all references to BAR will be asserted or assumed
    (with THE, so dependent on compiler policy) to involve objects of
    type FOO.  Note that no such declaration is implied in
    (MAKE-ARRAY .. :ELEMENT-TYPE 'FOO).
  * declared types of functions from the "Conditions"
    chapter. (reported by Paul Dietz)
  * bug fix: CERROR accepts a function as its first argument.
  * bug fix: NTH an NTHCDR accept a bignum as index
    arguments. (reported by Adam Warner)
  * optimization: character compare routines now optimize comparing
    against a constant character. (reported by Gilbert Baumann)
  * bug fix: (SETF AREF) on byte-sized-element arrays with constant index
    argument now works properly on the MIPS platform.
  * fixed compiler failure on (TYPEP x '(NOT (MEMBER 0d0))).
  * repeated evaluation of the same DEFSTRUCT, a slot of which is
    declared to have a functional type, does not cause an error
    anymore.
  * fixed bug: sometimes MAKE-INSTANCE did not work with classes with
    many :DEFAULT-INITARGS. (reported by Istvan Marko)
  * fixed bug: if last continuation of a deleted block has a
    destination, this destination should be deleted too. (reported by
    ohler on #lisp)
  * fixed a bug in the bootstrap process: the host compiler's values
    of ARRAY-DIMENSION-LIMIT and ARRAY-TOTAL-SIZE-LIMIT no longer leak
    into the newly-built SBCL. (reported by Eric Marsden on #lisp,
    test case from Patrik Nordebo)
  * improved the ability of the disassembler on the PPC platform to
    provide helpful disassembly notes.
  * SB-MOP:CLASS-PROTOTYPE on built-in-classes returns an instance of
    the class in more cases than previously.
  * bug fix: FILE-POSITION now understands :START and :END for
    STRING-INPUT-STREAMs.  (thanks to Nikodemus Siivola)
  * bug fix: (SIGNED-BYTE 8) streams no longer return (UNSIGNED-BYTE
    8) data.  (thanks to David Lichteblau)
  * bug fix: it is possible to add a method to a generic function
    without lambda list.
  * bug fix: reader failed to signal END-OF-FILE inside an
    object representation. (reported by Nikodemus Siivola)
  * fixed some bugs revealed by Paul Dietz' test suite:
    ** LAST and [N]BUTLAST should accept a bignum.
    ** condition slot accessors are methods.
    ** (VECTOR NIL) is a subtype of STRING.
