Log message:
Update gauche to 0.8.6.  Patch provided by Kenji Hisazumi.

>From this release we don't use external Boehm GC library because
gauche needs GC to be built with special compilation options.

New features in 0.8.6:

    * New modules:

	+ dbi: Database independent access layer, providing unified
	  access to various relational databases. You need separate
	  "driver" packages to access the actual RDBMS. There are a
	  few driver packages available at
	  http://www.kahua.org/cgi-bin/kahua.fcgi/kahua-web/show/dev/DBI/.
	    Note: If you have been using the separate dbi module, make
	    sure you remove it before using the new dbi and dbd
	    modules. You can find the old dbi.scm under somewhere like
	    /usr/local/share/gauche/site/lib (the actualy directory
	    depends on the configuration when you've installed the dbi
	    module).
	+ util.relation: A framework to work with relations (as defined
	  by Codd). The result of database access via dbi is represened as
	  a relation.
	+ text.sql: SQL parser/constructor. Full features are not
	  implemented yet, but used in dbi module for prepared queries.

    * New SRFIs:

	+ SRFI-40 (Library of streams) as util.stream.
	+ SRFI-43 (vector library) as srfi-43.
	+ SRFI-45 (Primitives for Expressing Iterative Lazy
	    Algorithms) : built-in.

    * New built-in proceduers global-variable-bound? and
      glboal-variable-ref. The former supersedes symbol-bound? (
      symbol-bound? is now deprecated and will go away in the future
      releases. Code that uses symbol-bound? should change it to
      global-variable-bound?. ). The latter removes some need of using
      eval just to peek the value of the global variable.

    * New regexp procedures: regexp-replace*, regexp-replace-all*,
      regexp-case-fold?.

    * Stack overflow handling is largely improved. You can see better
      performance if your script frequently oveflows the stack.

0.8.5 was a maintainance release.

0.8.4:

Gauche 0.8.4:

The compiler and VM have been rewritten. Now Gauche runs faster with
less memory (as fast as 1.9x, or cosumes 0.7x memory, in best cases of
our tests. But your mileage may vary.) The compiler now does simple
closure optimization, so the typical loop-by-local-closure style code
will get the advantage. On the other hand, you won't see much gain in
OO-heavy or library-heavy programs.

Other changes:

    * New features:

	  + srfi-42 (Eager comprehension) is supported.
	  + srfi-55 (require-extension) is supported.
	  + A simple sampling profiler is implemented to help tuning
	    programs. Check out "Profiling and tuning" section of the
	    reference manual. The profiler may not be available on all
	    platforms.
	  + We provide an experimenal Windows/MinGW binary package for
	    the convenience. See download page.

    Gauche 0.8.3: Bug fix release

    It turned out that 0.8.2's source-code encoding detection feature had a
    bug; if you're using Windows-style (CRLF) line-separator, the coding-aware
    port repeats one character at the beginning of the second line. It doesn't
    do any harm if first few lines of your code are comments, but it's annoying
    when you stumbled on it, so I decided to release a fixed version.

    This release also includes a couple of improvements: The coding-aware ports
    recognizes Emacs-style coding name (e.g. euc-jp-unix) and just ignores the
    Emacs-specific suffix (e.g. -unix). And external representations of
    f32vector and f64vector are now accurate.

    Gauche 0.8.2: Major revision of infrastructure.

     * New features
         - A condition (exception) system a la srfi-35 and (part of) srfi-36
            is supported. Used with guard (srfi-34), now it is possible to
            handle exceptions in more comprehensive way. See the \ 
"Exception"
            section of the manual, which has been rewritten accordingly.
         - Source-code encoding detection. Now Gauche recognizes a special
            comment like "coding: utf-8" near the beginning of the \ 
source file,
            and use appropriate conversion to load the source file. See
            "Multibyte Script" section of the manual for the details. This
            feature alone can be used independently from loading programs, via
            coding-aware ports, so the programs that processes Scheme scripts
            can also recognize the special comments.
         - Virtual ports are supported. Virtual ports are the ports whose
            behavior can be customized in Scheme. See the description of
            gauche.vport module in the manual for the details.
     * Improvements
         - Updated GC to Boehm GC 6.3. It fixes some GC-related problems on
            64bit architectures.
         - gauche.fcntl: F_GETOWN and F_SETOWN are supported, if the system
            provides them.
         - gauche.termios: c_cc field of struct termios is now accessible from
            Scheme. (Thanks to Kogule Ryo).
         - gauche.uvector: Added string->s8vector! and string->s8vector!.
            TAGvector-copy!'s API is changed so that it matches with srfi-13's
            string-copy! and srfi-43's vector-copy!.
         - Port implementation is cleaned up. Now line count is available not
            only for file ports but any ports (as far as it's doing character I
            /O). byte-ready? is added for binary I/O polling.
         - text.csv: quote character is customizable.
     * Bug fixes
         - INCOMPATIBLE CHANGE: The previous version's rfc.mime's API was
            broken. It couldn't handle MIME part whose message was non-encoded
            binary. Now MIME part stream parser is re-implemented using virtual
            ports, and the reader argument passed to the MIME part handler is
            dropped. www.cgi is also affected if you're using customized
            handler for file uploads. See the reference manual for the new API.
         - SONAME of the library is now set, if the platform supports it.
         - gauche.array: Some functions were not exported, although they were
            mentioned in the manual.
         - gauche.charconv: Fixed a bug in converting 2nd plane of JIS.
         - gauche.regexp: regexp-replace-all looped infinitely for some
            patterns. Now it raises an error.
         - dbm.fsdbm: It couldn't store binary data.
         - rfc.822: rfc822-parse-date returned wrong month number (off by
            one).
         - util.match: Fixed a bug in quasipattern. The description of
            quasipatterns in the reference manual is also revised to explain it
            better.
         - srfi-19: date->julian-day didn't recognize tz-offset.
         - Some bugs in numeric code are fixed.
         - let-args had a bug in parameter handling of 'else' clause.
         - directory-list: when :filter-add-path? is true, there was a bug
            that "." and ".." were included in the results \ 
even :children?
            argument was true.
         - There was a bug that causes an infinite loop during class
            redefinition.
         - let-keywords*: fixed a bug that corrupts expansion when used in
            r5rs macro.
     * C API Change
         - Class initialization API is overhauled. Scm_InitBuiltinClass is
            obsoleted; use Scm_InitStaticClass instead.
         - Port structure is changed quite a bit.
         - Functions to convert Scheme integers to C integers are revised, to
            handle out-of-range error in more flexible way.
         - API of Scm_Load, Scm_LoadFromPort and related functions are changed
            to support more flags.
