sbcl-0.8.3 released

Version 0.8.3 of SBCL has been released and is available on the
SourceForge file releases page. Enjoy!

from the NEWS file in the distribution:
changes in sbcl-0.8.3 relative to sbcl-0.8.2:
  * SBCL now builds and runs on MacOS X (version 10.2), or perhaps
    more accurately, on the Darwin kernel running on PowerPC hardware.
    (thanks to Brian Mastenbrook, Pierre Mai and Patrik Nordebo)
  * Compiler code deletion notes now signal a condition of type
    SB-EXT:CODE-DELETION-NOTE (a subtype of SB-EXT:COMPILER-NOTE) with
    an associated MUFFLE-WARNING restart.
  * The compiler now performs limited argument count validation of
    constant format strings in FORMAT, and where appropriate in ERROR, 
    CERROR and WARN.  (thanks to Gerd Moellmann)
  * New ASDF-INSTALL contrib can be used for automatic download and 
    installation of third-party Lisp code from CCLAN or other sites
    via CLiki.
  * Threaded builds (:SB-THREAD) now support SB-THREAD:INTERRUPT-THREAD,
    which forces another thread to execute a function supplied by the
    caller.
  * bug 75 fix: WITH-OUTPUT-TO-STRING (and MAKE-STRING-OUTPUT-STREAM)
    now accept and act upon their :ELEMENT-TYPE keyword argument.
    (reported by Martin Atzmueller, Edi Weitz)
  * bug fix: FILE-POSITION now accepts position designators up to
    ARRAY-DIMENSION-LIMIT or the extreme of the off_t range, whichever
    is the greater.  (thanks to Patrik Nordebo)
  * bug fix: MAKE-ARRAY ignored :INITIAL-CONTENTS NIL. (reported by
    Kalle Olavi Niemitalo)
  * bug fix: the CLASS-PROTOTYPE of the GENERIC-FUNCTION class is now
    printable.  (reported by Eric Marsden)
  * bug fix in sb-posix: mmap() now works on systems with a 64-bit
    off_t, including Darwin and FreeBSD.  (thanks to Andreas Fuchs)
  * x86 bug fix in control stack exhaustion checking: now shows backtrace
  * bug fix in WITH-TIMEOUT: now the body can have more than one form.
    (thanks to Stig Sandoe)
  * bug fix in READ-SEQUENCE: READ-SEQUENCE following PEEK-CHAR or
    UNREAD-CHAR now correctly includes the unread character in the
    target sequence.  (thanks to Gerd Moellmann)
  * bug fix in threaded builds: the system can now be suspended and
    resumed by shell job control with minimal disruption.
  * bug fixes in times and timezones >2038AD
  * better handling of "where is GNU make?" problem in build scripts
    (thanks to Nikodemus Siivola)
  * new optimization: inside a named function any reference to a
    function with the same name is considered to be a self-reference;
    this behaviour is controlled with SB-C::RECOGNIZE-SELF-CALLS
    optimization quality.
  * new optimization on x86: logical functions and + now have
    optimized (UNSIGNED-BYTE 32) versions, which are automatically
    used when the result is truncated to 32 bits.
  * VALUES declaration is partially enabled.
  * fixes in SB-GROVEL (thanks to Andreas Fuchs)
  * fixed some bugs revealed by Paul Dietz' test suite:
    ** The system now obeys the constraint imposed by
       UPGRADED-ARRAY-ELEMENT-TYPE that the upgraded array element
       types form a lattice under type intersection.
    ** FFLOOR, FTRUNCATE, FCEILING and FROUND work with integers.
    ** ASSOC now ignores NIL elements in an alist.
    ** CEILING now gives the right answer with MOST-NEGATIVE-FIXNUM
       and (1+ MOST-POSITIVE-FIXNUM) answers.
    ** The addition of a method with invalid qualifiers to a generic
       function does not cause an error to be signalled immediately;
       a warning is signalled, and the error is generated only on
       calling the generic function.
  * changed .fasl file version number, in part to add type codes for
    new array subtypes UNSIGNED-BYTE 7, 15, 29, and 31 mandated by 
    obscure ANSI requirements
