GCC fails to compile the attached file
as follow:

~/tmp % gcc-3.0 c2.cc                                                
c2.cc: In function `int main()':
c2.cc:20: `ret' is not a member of type `C<1, 2>::output<D<8, 1> >'
c2.cc:20: parse error before `;' token
The on-line C/C++ Comeau compiles it just fine.
>How-To-Repeat:
Compile the attached file.
