Update to SBCL 1.0.45

New in version 1.0.45

  * enhancement: ~/ and ~user/ are treated specially in pathnames.
  * enhancement: ASDF has been updated to version 2.010.
  * optimization: mutated closed-over variables that are only accessed
    by DYNAMIC-EXTENT closures (currently only FLET and LABELS functions
    declared to be DYNAMIC-EXTENT) are stored directly in their containing
    stack frame, rather than allocating a VALUE-CELL (#586103).
  * optimization: UNWIND-PROTECT cleanup functions are now declared
    DYNAMIC-EXTENT.

  Bug fixes.


New in version 1.0.44

  * enhancement: RUN-PROGRAM accepts :EXTERNAL-FORMAT argument
    to select the external-format for its :INPUT, :OUTPUT, AND
    :ERROR :STREAMs.
  * enhancement: ALLOCATION-INFORMATION also provides the page
    the object resides on.
  * enhancement: default dynamic-space size can be configured at
    build-time without touching source, using the --dynamic-space-size
    argument to make.sh.
  * enhancement: DESCRIBE recognizes symbols naming optimization
    policy qualities, and mentions ALWAYS-BOUND declarations.
  * enhancement: ATOMIC-INCF now supports AREF of
    (SIMPLE-ARRAY SB-EXT:WORD (*)) as a place.
  * enhancement: ASDF has been updated to 2.009.
  * enhancement: the system detects known type-erros in calls better,
    signalling a full warning about violated proclaimed FTYPEs and
    violations of derived FTYPEs within the same file, including self-calls.
  * enhancement: new function: SB-EXT:DELETE-DIRECTORY is now provided.
  * optimization: constant-folding exploits numeric and character types,
    in addition member types.
  * optimization: numeric, character and member types that are inhabited
    by exactly one value are tested with EQL.
  * optimization: more conditional branches are eliminated during IR1.
    Branches are simplified before performing if/if-conversion,
    and simple equivalent branches (that only read the same constant
    or variable) are merged.
  * improvements to the Windows port:
      + change: canonical unparsing form for pathname namestrings now
        uses / as directory separator. NATIVE-NAMESTRING still uses \
        as the separator.
      + bug fix: stackoverwriting due to incorrect usage of PeekConsoleInput
        on Windows. (thanks to Kalyanov Dmitry)
      + bug fix: build now works on cygwin with GCC 4.x installed.
      + bug fix: run-sbcl.sh now works on Cygwin. (thanks to Kalyanov Dmitry)

  Bug fixes.


New in version 1.0.43

  * incompatible change: FD-STREAMS no longer participate in the
    serve-event event-loop by default. (#316072)
      + In addition to streams created by explicit calls to MAKE-FD-STREAM
        this affects streams from CL:OPEN.
      + Streams from SOCKET-MAKE-STREAM still participate in
        serve-event by default, but this is liable to change:
        applications  needing serve-event for socket streams
        should explicitly request it using :SERVE-EVENTS T in the call.
  * enhancement: SB-EXT:WORD type is provided for use with
    SB-EXT:ATOMIC-INCF &co.
  * enhancement: CLOS effective method functions and defclass slot
    typechecking function now have debug names for use in backtraces
    and profiles.
  * enhancement: ASDF has been updated to version 2.004.
  * enhancement: symbols are printed using fully qualified names
    in several error and warning messages which are often associated
    with package conflicts or mixups (#622789, thanks to Attila Lendvai)

  Bug fixes.
