We had the same problem with TADODataSet in CBuilder. We found a workaround 
by using a "wrapper class".

class TMyDataSet : public TADODataSet
{
private:

protected:

public:
  __fastcall virtual TMyDataSet (Classes::TComponent* AOwner);
  __fastcall virtual ~TMyDataSet (void);
};

__fastcall TMobaDataSet::TMobaDataSet(Classes::TComponent* AOwner)
  : TADODataSet(AOwner)
{
}

__fastcall TMobaDataSet::~TMobaDataSet(void)
{
}

Create a TMyDataSet object though new operator:
  TMyDataSet* objDataSet = new TMyDateSet(NULL);

Other way to solve the problem is to use TADOQuery in stead of TADODataSet.
In CBuilder 'new TADOQuery(NULL)' does not give problems with codeguard
