// We need to disable warning 4910 and do an extern dllexport

// instantiation of this template the compiler does an explicit
// instantiation of the base class.  From outside the vtkCommon
// library we block this using an extern dllimport instantiation.
// For classes inside vtkCommon we should be able to just do an
// extern instantiation, but VS 2008 complains about missing
// definitions.  We cannot do an extern dllimport inside vtkCommon
// since the symbols are local to the dll.  An extern dllexport
// seems to be the only way to convince VS 2008 to do the right
// thing, so we just disable the warning.
