bug in MFC 4.1

     Environment: VC++ 4.1, Win95/NT
     
     I believe I've located a bug in MFC 4.1.  It's probably already been 
     fixed but I'll check.
     
     In the function 
     
     void AFXAPI DDX_Text(CDataExchange* pDX, int nIDC, short& value)
     
     defined on line 205 of dlgdata.cpp, a format specifier is passed to 
     DDX_TextWithFormat- "%d".  This needs to be "%sd", because, the way it 
     stands, AfxSimpleScanf(), which is eventually called by this routine, 
     thinks the short passed to it is a 4 byte int and writes 4 bytes to 
     it.
     
     I discovered this bug by using ClassWizard to associate a variable of 
     type short with an edit control's value.
