-** Marshal(モジュール)
-
-rubyオブジェクトをファイルに書き出したり，読みも度したりする機能を提供
-するモジュール．大部分のクラスのインスタンスを書き出す事ができるが，ファ
-イルへの不可能なクラスも存在し(例:IO)，そのようなクラスを書き出そうと
-すると例外を発生させる．
-
-Methods:
-Single Methods:
-
-   dump(obj, port[, limit])
-
-    objを再帰的にファイルに書き出す．ファイルに書き出せないクラスのイ
-    ンスタンスをファイルに書き出そうとすると例外を発生させる．ファイル
-    に書き出せないクラスは以下の通り．
-
-	Class, Module, Data
-
-    また，これらのクラスを間接的に指すクラス(例えばIOのサブクラス)など
-    も書き出せない．portはIO(またはそのサブクラス)のインスタンスを指定
-    する．
-
-    出力するオブジェクトがメソッド`_dump_to'を定義している場合には，ファ
-    イル出力はそのメソッドを使って行われる．メソッド`_dump_to'は引数と
-    して出力先のファイルオブジェクトを受け取る．インスタンスがメソッド
-    `_dump_to'を持つクラスは必ず同じフォーマットを読み戻す特異メソッド
-    `_load_from'を定義する必要がある．
-
-    limitを指定した場合，limit段以上深くリンクしたオブジェクトをダンプ
-    できない(デフォルトは100レベル)。負のlimitを指定すると深さチェック
-    を行わない。
-
-   dumps(obj)
-
-    dump()がファイルに書き出すのと同じ内容を含む文字列を返す．
-
-   load(port)
-
-    portからオブジェクトを読み込んで来て，元のオブジェクトと同じ状態を
-    もつオブジェクトを生成する．portは文字列かIO(またはそのサブクラス)
-    のインスタンスである．

-/* alloca -- (mostly) portable public-domain implementation -- D A Gwyn
-
-   last edit:	86/05/30	rms
-   include config.h, since on VMS it renames some symbols.
-   Use xmalloc instead of malloc.
-
-   This implementation of the PWB library alloca() function,
-   which is used to allocate space off the run-time stack so
-   that it is automatically reclaimed upon procedure exit, 
-   was inspired by discussions with J. Q. Johnson of Cornell.
-
-   It should work under any C implementation that uses an
-   actual procedure stack (as opposed to a linked list of
-   frames).  There are some preprocessor constants that can
-   be defined when compiling for your specific system, for
-   improved efficiency; however, the defaults should be okay.
-
-   The general concept of this implementation is to keep
-   track of all alloca()-allocated blocks, and reclaim any
-   that are found to be deeper in the stack than the current
-   invocation.  This heuristic does not reclaim storage as
-   soon as it becomes invalid, but it will do so eventually.
-
-   As a special case, alloca(0) reclaims storage without
-   allocating any.  It is a good idea to use alloca(0) in
-   your main control loop, etc. to force garbage collection.

- * Suffix appending for in-place editing under MS-DOS and OS/2 (and now NT!).
- *
- * Here are the rules:
- *
- * Style 0:  Append the suffix exactly as standard perl would do it.
- *           If the filesystem groks it, use it.  (HPFS will always
- *           grok it.  So will NTFS. FAT will rarely accept it.)
- *
- * Style 1:  The suffix begins with a '.'.  The extension is replaced.
- *           If the name matches the original name, use the fallback method.
- *
- * Style 2:  The suffix is a single character, not a '.'.  Try to add the 
- *           suffix to the following places, using the first one that works.
- *               [1] Append to extension.  
- *               [2] Append to filename, 
- *               [3] Replace end of extension, 
- *               [4] Replace end of filename.
- *           If the name matches the original name, use the fallback method.
- *
- * Style 3:  Any other case:  Ignore the suffix completely and use the
- *           fallback method.
- *
- * Fallback method:  Change the extension to ".$$$".  If that matches the
- *           original name, then change the extension to ".~~~".
- *
- * If filename is more than 1000 characters long, we die a horrible
- * death.  Sorry.
- *
- * The filename restriction is a cheat so that we can use buf[] to store
- * assorted temporary goo.
- *
- * Examples, assuming style 0 failed.
- *
- * suffix = ".bak" (style 1)
- *                foo.bar => foo.bak
- *                foo.bak => foo.$$$	(fallback)
- *                foo.$$$ => foo.~~~	(fallback)
- *                makefile => makefile.bak
- *
- * suffix = "~" (style 2)
- *                foo.c => foo.c~
- *                foo.c~ => foo.c~~
- *                foo.c~~ => foo~.c~~
- *                foo~.c~~ => foo~~.c~~
- *                foo~~~~~.c~~ => foo~~~~~.$$$ (fallback)
- *
- *                foo.pas => foo~.pas

- *
- * Public-domain implementation of ANSI C library routine.
- *
- * It's written in old-style C for maximal portability.
- * However, since I'm used to prototypes, I've included them too.
- *
- * If you want stuff in the System V ascftime routine, add the SYSV_EXT define.
- * For extensions from SunOS, add SUNOS_EXT.
- * For stuff needed to implement the P1003.2 date command, add POSIX2_DATE.
- * For VMS dates, add VMS_EXT.
- * For a an RFC822 time format, add MAILHEADER_EXT.
- * For ISO week years, add ISO_DATE_EXT.
- * For complete POSIX semantics, add POSIX_SEMANTICS.
- *
- * The code for %c, %x, and %X now follows the 1003.2 specification for
- * the POSIX locale.
- * This version ignores LOCALE information.
- * It also doesn't worry about multi-byte characters.
- * So there.
- *
- * This file is also shipped with GAWK (GNU Awk), gawk specific bits of
- * code are included if GAWK is defined.

-Hi Arnold,
-in a process of fixing of strftime() in libraries on Atari ST I grabbed
-some pieces of code from your own strftime.  When doing that it came
-to mind that your weeknumber() function compiles a little bit nicer
-in the following form:
-/*
- * firstweekday is 0 if starting in Sunday, non-zero if in Monday
- */
-{
-    return (timeptr->tm_yday - timeptr->tm_wday +
-	    (firstweekday ? (timeptr->tm_wday ? 8 : 1) : 7)) / 7;
-}
-How nicer it depends on a compiler, of course, but always a tiny bit.
-
-   Cheers,
-   Michal
