XMFC is an EXPERIMENTAL version of MFC 2.5 that introduces support for virtual
inheritance of CObject and CWnd. In effect, the limitations cast by TN 16
are lifted. It is now possible to derive from both CFrameWnd and CDialog, or
write 'mixin' classes.
XMFC also improves the emulation of exception. Destructors are called when
an exception is thrown for any stack object of CObject-derived class.
XMFC is free and comes with no guarantee whatsoever.
