It seems so, but how come that linking fails only with mingw? There is
also an explicit instantiation inside
itkSmartPointerForwardReferenceProcessObject.cxx which is used
like this in CMakeLists.txt:

IF (WIN32)
   SET(ITKCommon_SRCS ${ITKCommon_SRCS} itkWin32OutputWindow.cxx itkSmartPointerForwardReferenceProcessObject.cxx)
ENDIF (WIN32)

If you have any ideas I can test it because right now i have access to
one mingw-windows machine.
