压缩解压,是unzip540的升级,这个外国网站摘来的源码,是evb编写.

        If you want to force the use of VAX C when both VAX C and DEC C are
        available, do "@make_unz vaxc" (or "@[.vms]make_unz vaxc").
        To use GNU C (gcc) on either platform, do "@make_unz gnuc".
        (NOTE: Currently, gcc for VMS(AXP) is not yet available!)
        The command procedure MAKE_UNZ.COM now recognizes custom feature
        options supplied in the logical name LOCAL_UNZIP; details are
        explained in the comments at the top of MAKE_UNZ.COM.

        For repeated makes or other hacker-like tinkering with the sources,
        or to create a custom version of UnZip, you may use the included "MMS"
        makefile, DESCRIP.MMS.  Copy it into the current directory, read the
        comments at the top of it and run MadGoat's free MMS clone "MMK" on it.
        Newer versions of DEC's MMS should work, too, but older ones apparently
        choke on some MMK-specific extensions in DESCRIP.MMS.  (If somebody
        has an "older" version that works, let us know and we'll remove this
        caveat.)

      MS-DOS
        See the msdos\Contents file for notes regarding which makefile(s) to
        use with which compiler.  In summary:  pick one of msdos\makefile.*
        as appropriate, or (as noted above) use the OS/2 gccdos target for
        emx+gcc.  There is also an mscdos cross-compilation target in
        os2\makefile.os2 and a sco_dos cross-compilation target in the Unix
        makefile.  For Watcom 16-bit or 32-bit versions, see the comments in
        the OS/2 section below.

        After choosing the appropriate makefile and editing as necessary or
        desired, invoke the corresponding make utility.  Microsoft's NMAKE
        and the free dmake and GNU make utilities are generally the most
        versatile.  The makefiles in the msdos directory can be invoked in
        place ("nmake -f msdos\makefile.msc", for example).

      OS/2
        Either GNU make, nmake or dmake may be used with the OS/2 makefile;
        all are freely available on the net.  Do "nmake -f os2\makefile.os2",
        for example, to get a list of supported targets.  More generally,
        read the comments at the top of the makefile for an explanation of
        the differences between some of the same-compiler targets.

      Win32 (WinNT or Win95)
        You will need Microsoft Visual C++ 2.x for Win95 or NT (Intel, MIPS,
        Alpha, PowerPC?), or Watcom C++ for Win95 or NT (Intel only). As an
        alternative for Intel platforms, GNU C (the emx/rsxnt port) is now
        supported as well. DEC C/C++ for NT/Alpha may or may not still work.
        For the Watcom compiler, use WMAKE and win32\makefile.wat; for the
        others, use NMAKE and win32\Makefile. With emx+gcc, a good choice is
        GNUMake 3.75 from the djgpp V2.01 distribution.

      WinCE (WinCE or WinNT)
        Only Microsoft Visual C++ 5.0 or later is supported.  Use the included
        project file and check wince\README for details.

      AmigaDOS
        SAS/Lattice C and Manx Aztec C are supported.  For SAS C 6.x do "smake
        -f amiga/smakefile all"; for Aztec C do "make -f amiga/makefile.azt
        all".  The Aztec C version supports assembly-language versions of two
        routines; these are enabled by default.

      Atari TOS
        Turbo C is no longer supported; use gcc and the MiNT libraries, and
        do "make".  Note that all versions of gcc prior to 2.5.8 have a bug
        affecting 68000-based machines (optimizer adds 68020 instructions).
        See atari\README for comments on using other compilers.

      Macintosh
        Metrowerks CodeWarrior Pro 4 with Universal Interfaces 3.1 is the only
        currently supported compiler, although the Mac Programmer's Workbench
        (MPW) and Think C were supported at one time and still have some hooks.
        Other Compilers may work too, no compiler specific instructions
        (pragma, header, macros, ...) were used in the code.
        For CodeWarrior Pro 4, un-BinHex the CodeWarrior project file and
        UnZip resource file (using Stuffit Expander or BinHex 4.0 or later),
        then open the project and click on the compile button.
        See ":macos:Contents" for the possible project targets.
        Link order of the standard libraries is very important: Link all
        sources first and all standard libraries last.

      Acorn (RISC OS)
        Extract the files from the archive and place in standard 'Acorn' C
        form (i.e., *.c, *.h and *.s become c.*, h.* and s.*, respectively),
        either using the UNZIP$EXTS environment variable and a pre-built UnZip
        binary, or using Spark[FS] and doing it manually.  Then copy the
        Acorn.Makefile to the main UnZip directory and either type 'amu' or
        use the desktop make utility.

      VM/CMS
        Unpack all the files and transfer them with ASCII -> EBCDIC conver-
        sion to an appropriate directory/minidisk/whatever, then execute
        UNZVMC to compile and link all the sources.  This may require C/370
        version 2.1 or later and certain `nucleus extensions,' although
        UnZip 5.3 has been reported to compile fine with the `ADCYCLE C/370
        v1.2 compiler.'  Note that it will abend without access to the C/370
        runtime library.  See the README.CMS file for more details.

      MVS
        Unpack all the files and transfer them to an appropriate PDS with
        ASCII -> EBCDIC conversion enabled, then edit UNZMVSC.JOB as required,
        and execute it to compile and link all the sources.  C/370 2.1 or
        later is required.  See README.MVS for further details.  [This is a
        new port and may need a little more work even to compile.]

      Human68K
        [This is a Japanese machine and OS.]  It appears that GNU make and
        gcc are required; presumably just do "gmake -f human68k/Makefile.gcc"
        to build everything.  This port has not been tested since the 5.12
        release.

      TOPS-20
        [No longer fully supported due to new, unported features, although
        patches are always accepted.]  Unpack all files into the current
        directory only (including those in the zipfile's tops20 directory),
        then use make.mic and "do make".

      BeOS
        You can run the BeOS makefile in place by typing "make -f
        beos/Makefile".  In fact, this is how the author tests it.

    Running the appropriate make utility should produce three executables on
    most systems, one for UnZip/ZipInfo, one for UnZipSFX, and one for fUnZip.
    (VMS is one prominent exception:  fUnZip makes no sense on it.  The Amiga
    produces a fourth executable called MakeSFX, which is necessary because
    Amiga self-extracting archives cannot be created by simple concatenation.
    If necessary the source amiga/makesfx.c can be compiled on other systems.)
    Read any OS-specific README files for notes on setting things up for
    normal use (especially for VMS) and for warnings about known quirks and
    bugs in various compilers (especially for MS-DOS).

    Also note that many OSes require a timezone variable to be set correctly
    (often "TZ"); Unix and VMS generally do so by default, Win95/NT do if set
    up properly, but other OSes generally do not.  See the discussion of the
    -f and -u options in the UnZip man page (or unzip.txt).  BeOS doesn't
    currently support timezone information at all, but this will probably be
    added soon.

    Then test your new UnZip on a few archives and let us know if there are
    problems (but *please* first make certain that the archives aren't actu-
    ally corrupted and that you didn't make one of the silly mistakes dis-
    cussed in the documentation).  If possible, double-check any problems
    with PKUNZIP or with a previous version of UnZip prior to reporting a
    "bug."  The zipfile itself may be damaged.



To install:
===========

Unix
  The default prefix for the installation location is /usr/local (things
  go into the bin and man/man1 subdirectories beneath the prefix), and
  the default man-page extension is "1" (corresponding to man/man1, above).
  To install as per the defaults, do "make install"; otherwise do "make
  prefix=/your/path manext=your_extension install".  (For Intel Unix flavors
  where the assembler CRC routines were used [ASM_CRC], use the install_asm
  target instead of the regular install target.)  For example, to install
  in your home directory with "l" as the man-page extension (for "local"),
  do "make prefix=$HOME manext=l install".  Permissions will be 755 for the
  executables and 644 for the man pages.  In general root must perform in-
  stallation into a public directory.  Do "rehash" if your shell requires
  it in order to find the new executables.

VMS
  Install UnZip as foreign symbol by adding this to login.com:

       $ unzip == "$disk:[dir]unzip.exe"
       $ zipinfo == "$disk:[dir]unzip.exe ""-Z"""

  where "disk" and "dir" are the location of the UnZip executable; the "$"
  before the disk name is important, as are the double-double-quotes around
  the -Z.  Some people, including the author, prefer a short alias such as
  "ii" instead of "zipinfo"; edit to taste.  Optionally also install unzipsfx
  for use with the MAKESFX.COM command file.  See vms/README (or [.VMS]README.)
  for details on this and for notes/warnings about zipfiles and UnZip under
  VMS.

OS/2, MS-DOS, NT, Atari, Amiga
  Move or copy unzip.exe (or unzip.ttp, or UnZip, or whatever) to a direc-
  tory in your path; also possibly copy the UnZip executable to zipinfo.exe
  (or ii.exe), or else create an alias or a batch/command file for ZipInfo
  ("@unzip -Z %1 %2 %3 %4 %5 %6 %7 %8 %9" under MS-DOS).  The latter is only
  relevant if NO_ZIPINFO was *not* defined, obviously...  Under djgpp 2.x,
  zipinfo.exe is a 2K stub symbolically linked to unzip.exe.

Acorn RISC OS
  Copy the executables unzip, funzip and zipinfo to somewhere in your
  Run$Path.  See your Welcome manual if you don't know about Run$Path.

BeOS
  The default prefix for the installation location is /boot/usr/local
  (things go into the bin and man/man1 subdirectories beneath the prefix),
  and the default man-page extension is "1" (corresponding to the man/man1,
  above).  Of course, these Unix man-pages aren't useful until someone ports
  something that can format them... plain text versions are also installed
  with an extension of ".txt".  To install, do a "make install", or to
  change the prefix, do "make prefix=/your/path install".  For example, to
  install in /boot/bin, do "make prefix=/boot/bin install".

Macintosh
  MacZip requires at least System 7 and a Macintosh with a minimum of a
  Motorola 68020 or PowerPC 601 processor. Other configurations may work
  but it is not tested at all.
  The application (MacZip) is distributed as a combination of zip and unzip
  in one program. The offical release is a fat binary with both regular 68K
  and native PowerPC versions included.
  Move the executable(s) somewhere--for example, drag it (or them) to your
  Applications folder.  For easy access, make an alias in the Launcher Control
  Panel or directly on your desktop.
  This port supports also Apple-event.So you can install it in your
  WWW-Browser as a helper-app.
  Look into "macos/README.TXT" (or ":macos:README.TXT" on Mac) for further
  info.

Human68K, TOPS-20, AOS/VS, MVS, VM/CMS, etc.
  Dunno, sorry...
