        + add some redundant pointer checks, e.g., to entry.c, to avoid core
          dump if one tries building Cdk with NetBSD curses (see lib/32417).
        + split up traverseCDKScreen() to allow customized flavors of that to
          be written in a calling application using the pieces: 
          traverseCDKOnce(), setCDKFocusFirst() (request by Jorgen Lundman).
        + restore assignment of selectedItem in setCDKRadioCurrentItem() which
          was dropped in 2005/04/24 (report by Fu Steve X).
        + modify refreshCDKScreen() to ensure that only one widget will have
          focus, i.e., the first which currently has focus, or if none, then
          the first visible one (report by Fu Steve X).
        + use cleanCDKTemplate() consistently in the template widget, ensuring
          that the editing position is updated, and that the proper length is
          used when clearing memory (report by Fu Steve X).
        + modify calendar, radio, scroll, selection widgets so the cursor is
          shown at the beginning of the selected item's row for better
          accessibility (report by Fu Steve X).
        + add null-pointer check in setCDKViewerInfo() in case caller gives
          too-large value for list size (report by Jorgen Lundman).
        + improve traverseCDKScreen() by updating curobj from the
          getCDKFocusCurrent() function (patch by Jorgen Lundman).
        + add setCDKFocusCurrent() (patch by Jorgen Lundman).
        + add configure script option allowing manpage section to be changed
          from "3" to other values such as "3CDK", e.g., for Debian.
        + modify getCDKRadioItems(), getCDKScrollItems() and
          getCDKSelectionItems() to return just the list-size if the list
          pointer is null.
        + correct highlighting of selected line in CDKSelection window when
          the window is scrolled left/right (patch by Jorgen Lundman).
        + various manpage fixes (report by Jorgen Lundman).
        + change manpages to use ".XX" macro to indicate aliases, to make
          the manpage more readable.
        + eliminate duplication between cdk_util.3 and cdk_misc.3 manpages
          (dialogs belong in the former, for instance).
        + modify alphalist, itemlist, radio, selection and swindow to allow
          creating a widget with an empty list (request by Harry Brueckner).
        + modify mentry.c case for KEY_RIGHT so one can move the cursor past
          the end of the string to add new text (report by Harry Brueckner).
        + modify cdk_params.c to use strtol() rather than atoi() to allow
          command-line parameters such as -h 0xffff for the slider examples.
        + modify gen-slider.c to use sprintf/strlen to obtain length of
          formatted integer types since intlen() does not give correct result
          for maximum value of unsigned type.  Modify increment/decrement logic
          to take into account unsigned types (report by Keith J Outwater).
        + modify cli examples to exit with 255 when reporting an error rather
          than a -1 which is generally not portable.
        + fix several memory leaks exposed by valgrind in the example programs.
        + add configure --disable-leaks option to look for ncurses' debug
          function _nc_free_and_exit(), using that to help with memory leak
          checking.  This uses a new header <cdk_test.h> which will not be
          installed, since it is used only for testing in the build tree.
        > patches by Phuah Yee Keat:
          + add an IsVisibleObj attribute to all CDK objects so the caller can
            set some object to be invisible, and calling refreshCDKScreen
            after that won't display it again, it enables one to dynamically
            show or hide a particular widget based on user actions.
            Note: this changes alignments in many of the structs from 5.0,
            requiring an ABI bump.
          + improve string length-computation in entry.c, allowing a 1-char
            field, and also allowing movement past end of text with KEY_END.
          + add setCDKRadioSelectedItem() and getCDKRadioSelectedItem().
          + fix some memory leaks by adding cleanCDKObjBindings() into all of
            the _destroyXXX() functions, modify cleanCDKObjBindings() to free
            and null (obj)->bindingList.
        + fix makefile for installing manpages when building outside of the
          source directory (patch by Mike Castle).
        + remove obsolete lsm file
        + review/correct some functions listed in manpages but not implemented,
          and the reverse (report by Rajat Das).
        + add setCDKMatrixCB() (report by 'zam).
        + update configure script (mostly fixes related to CF_XOPEN_SOURCE).
        + update config.guess, config.sub
