1.0 Notes about the source code

    1.1 Compiler support

        The 16 bit DOS version has been compiled with Borland C/C++
        4.02, but will also compile with Borland 3. A 16 bit DOS wcd
        can also be build with the Open Watcom compiler.

        The 32 bit dos versions are compiled with DJGPP and do not use
        DOSDIR. DJGPP is a mix of DOS/Unix compiler (both 'MSDOS' and
        'unix' are defined). DOSDIR's dd_findfirst/dd_findnext
        implementation for Unix is build with opendir/readdir. Using
        DJGPP's implementation of opendir/readdir to scan a disk is
        about a factor 100 slower than using findfirst/findnext (with
        DJGPP 2.01, gcc 2.7.2). Also using DOSDIR's
        dd_findfirst/dd_findnext for DOS is very slow when it is
        compiled with DJGPP. It is about a factor 35 slower than using
        DJGPP's findfirst/findnext. Probably due to a slow stat()
        function in dd_initstruct(). Using DOSDIR in combination with
        DJGPP would make scanning the disk very slow. A 32 bit DOS wcd
        can also be build with the Open Watcom compiler.

        The win32 console version is by default compiled with MinGW.
        Win32 versions can also be compiled with Borland, LCC, Open
        Watcom and Cygwin. Although Borland 4 can compile wcd with
        conio interface for windows console, it doesn't work well. The
        screen gets garbled after exit.

        Wcd for Unix compiles with gcc and with the native system C
        compilers such as HP-UX cc or SunOS cc.

    1.2 Curses support

        Wcd can optionally have a curse-based interface. Wcd compiles
        with curses, ncurses and pdcurses. Ncurses is preferred,
        because of portability and it restores the screen
        automatically after exit (if possible) and has better support
        for resizing of the terminal.

        The ncurses (new curses) library is a free software emulation
        of curses in System V Release 4.0, and more. It uses terminfo
        format, supports pads and color and multiple highlights and
        forms characters and function-key mapping, and has all the
        other SYSV-curses enhancements over BSD curses. The ncurses
        distribution is available via anonymous FTP at the GNU
        distribution site ftp://ftp.gnu.org/pub/gnu/ncurses. It is
        also available at ftp://ftp.clark.net/pub/dickey/ncurses.

        PDCurses is a port of System VR4 curses for multiple
        platforms. PDCurses has been ported to DOS, OS/2, X11, WIN32
        and Flexos. A directory containing the port-specific source
        files exists for each of these platforms. Get it at
        http://pdcurses.sourceforge.net/

    1.3 DOS DJGPP support

        DJGPP is a project to port the GNU C/C++ compiler to DOS.
        It includes a shell (bash) and many ported unix utilities.

    1.4 Cygwin support

        Cygwin is a project to port the GNU C/C++ compiler to Windows.
        It includes a shell (bash) and many ported unix utilities.
