XE5 instalation on XE7 problem with hpp and TTBPopupPositionRec

[eimix]

TB2Item.HPP is generated, after patching it has stuct TTBPopupPositionRec.
But C++ compiler complains:
**
[bcc32 Error] TB2Item.hpp(157): E2019 'TTBPopupPositionRec:: :: :: ()' cannot be declared in an anonymous union
TB2Item.hpp(135): class TTBPopupPositionRec::
**
Here it is generated struct:

struct DECLSPEC_DRECORD TTBPopupPositionRec
{
    union
    {
        struct 
        {
            bool HorzHideSeparators;
            int HorzWrapOffset;
            TTBOrientation PopupOrientation;
        };
        struct 
        {
            bool PositionAsSubmenu;
            TTBPopupAlignment Alignment;
            bool Opposite;
            System::Types::TRect MonitorRect;
            System::Types::TRect ParentItemRect;
            int NCSizeX;
            int NCSizeY;
            int X;
            int Y;
            int W;
            int H;
            Tb2anim::TTBAnimationDirection AnimDir;
            bool PlaySound;
        };

    };
};
