setCDKRadioCurrentItem in latest CDK

[Fu Steve X]

After the updating to cdk-5.0-20050424, my application quit working.  I found it was the function call:

        setCDKRadioCurrentItem(Radio, 0)

It is defined in the header file cdk_int.h as:     
        #define scroller_KEY_HOME(w) \
      (w)->currentTop   = 0; \
      (w)->currentItem = 0; \
      (w)->currentHigh = 0
Probably the attribute selectedItem is missing.

So I put the following to my code to work around it.
        Radio->selectedItem = 0;
      Radio->currentItem = 0;
      Radio->currentHigh = 0;
