This fails also with the same error, but:
------
#include "Array.h"
#include "Array.cc"
//template class ArrayRep<float>;   // works with or without 
//template class Array<float>;      // these
main(int argc, char *argv[])
{
  Array<float> a(10);
}
------
works (where Array.cc is from the liboctave directory).  I think
this is something to do with Implicit/Explicit Instantiation?

Thanks
Andrew
