The following construct leads VAView to display the common base class BaseData as direct base class of CommonData.
class BaseData 
{
public: 
  BaseData() {}
};
class DerivedData1 : public BaseData
{
public:
  DerivedData1() {}
};
class DerivedData2 : public BaseData
{
public:
  DerivedData2() {}
};

class CommonData: public DerivedData1, protected DerivedData2
{
}

Also: deriving a class from the struct OVERLAPPED (win32 sdk) shows both _OVERLAPPED and OVERLAPPED as base classes.
OVERLAPPED is defined as "typedef struct _OVERLAPPED { ... } OVERLAPPED, *LPOVERLAPPED;"

apologies for the delay, i am starting to catch up on my backlog.

the fist post is:

case=2918

deriving from the OVERLAPPED struct is

case=2920
