sorry, i sent a bit misleading example - maybe you're right,
i'm reading CD2 now.

Still i believe there are bugs in template instantiation -
if you change superdummy in the atached test.ii to

void
superdummy( void ) {
  TVector3D<double> ccc, ddd;
  ccc = 1.0;
  abs(ccc);
  ccc = ccc + ddd;
}


egcs will not be able instantiate 
op+( const  TVector3D<double>&, const  TVector3D<double>&  ) !

drabble ~ $ nm -s test.o | c++filt | grep Vec
00000000 W TVector3D<double>::~TVector3D(void)
00000000 W TVector3D<double>::operator=(TVector3D<double> const &)
00000000 W TVector3D<double>::operator=(double)
         U operator+(TVector3D<double> const &, TVector3D<double> const &)
00000000 W TVector3D<double>::TVector3D(void)
         U abs(TVector3D<double> const &)


there is  no template/nontemplate op+ ix in the code.

Can you verify this one?

thanks

OK
