Update GNU Smalltalk to version 3.2.4

List of user-visible changes in GNU Smalltalk

NEWS FROM 3.2.3 TO 3.2.4

o   Autoload is extended to allow plugging in arbitrary loaders.

o   Array items in a CStruct didn't work, this is fixed now.

o   DLD could have problems when the same library was requested multiple
    times.

o   Errors in the bind() system call were not detected correctly; this
    has been fixed.

o   Fixes for platforms with 113-bit long doubles.

o   Fixes to Delay in the presence of delays with the exact same expiration.

o   Fixes to the HTTP package, including correct flushing of POST requests
    and doesNotUnderstand exceptions when the host did not exist.

o   GLUT bindings now build correctly under Windows.

o   Many smalltalk-mode improvements.

o   New methods: TextCollector>>#critical:,

o   nil can be passed to a C function accepting a #cObjectPtr (i.e.
    void **) argument.

o   SocketAddress>>#allByName: returns nil now, instead of an empty array,
    when getaddrinfo succeeds but returns no address for the requested
    address class.

o   SocketAddress>>#byName: returns addresses for the default address class
    when the receiver is SocketAddress (and not a subclass).

o   Support for older versions of GnuTLS.

o   Swazoo's static content serving was broken and has been fixed.

o   The GST_PACKAGE macro supports having multiple .la files in its last
    argument.  gst-package's --prepare option was broken and has been fixed.

o   The NetClients exception ProtocolError now includes the erroneous
    response.  Similarly, the package includes ProtocolNotification which
    is used, for example, for HTTP redirects.

o   Updated the Squeak/Pharo fileout parser.

o   Updated VisualGST.

-----------------------------------------------------------------------------

NEWS FROM 3.2.2 TO 3.2.3

o   Class attributes can have more than 1 keyword.

o   Documented #byteArrayOut C call argument passing mode.

o   Fixed crash when an invalid UnicodeString was created using
    #changeClassTo:

o   Fixed deadlock with #atEnd and two-way pipes.

o   Fixed bugs when adding instance variables to an existing class.

o   Fixed Socket>>#isPeerAlive falsely returning true.

o   Fixed some bugs in UTF-7 conversion.

o   FreeBSD port and 64-bit Darwin port.  The latter requires a
    pre-installed libsigsegv.

o   "gst-convert -f squeak" reads binary selectors with more than two
    characters; however they should be shortened with rewrite rules
    to use the output.

o   gst-doc can generate sensible documentation for a package if
    some of its prerequisite are not loaded, even if some of the
    package's classes subclass from the prerequisite.

o   GTK+ bindings are generated correctly for newer versions of GLib
    (tested up to 2.26).

o   If found, pre-installed libsigsegv, libffi and libltdl are used by
    default.

o   Improvements for Emacs mode.  Installation of Emacs mode detects
    Debian's /etc/emacs/site-start.d, and a --with-lispstartdir option
    is provided for distributions that are not Red Hat- or Debian-based.

o   Machine-specific optimizations for x86-64, and other microoptimizations
    resulting in small but consistent performance improvements.

o   More out of memory conditions are detected.

o   New methods: ByteArray>>#castTo:, ByteArray>>#asCData,
    String>>#asCData, UndefinedObject>>#inheritsFrom:

o   New goodie: Announcements.

o   Number class>>#readFrom: can parse numbers in scientific notation.

o   Package descriptions do not need to include a <file> item for each
    <filein> item.  However, it is still possible to include them for
    backwards compatibility, and it is possible to include a source file
    as both <filein> and <built-file> (so that gst-package --dist will
    skip it).

o   Packages can be downloaded using HTTPS if GnuTLS libraries are
    present.

o   Performance statistics printed by -V are now correct.

o   Scoped methods ("A class >> a") can be used in an "A class [ ... ]"
    block.

o   Semaphore>>#wait returns nil if the wait was interrupted externally
    (e.g. from Process>>#resume).

o   String>>#asCData: and String>>#asCData NULL-terminate their output.

o   Support for timeouts when waiting on a Semaphore.

o   Swazoo supports SCGI.  Its configuration however is still manual,
    since the Seaside and Iliad adaptors do not know about it.

o   Updated VisualGST.
