I don't have gcc 3.4.0 installed yet, but I've heard that gcc 3.40 is
much pickier about what it interprets as a typename. Therefore in the

template octave_sort<vec_index *>

gcc 3.4.0 doesn't interpret vec_index as a type and thus "<" and ">" are
interpreted as less and greater than. This explains the bizarre error
message. 

The solution is to explicitly tell gcc that vec_index is a typename with

template octave_sort<typename vec_index *>

I attach a patch for this, but as I say I don't have gcc 3.4.0 installed,
so I'd appreciate if you can test it.

Regards
David
