Defining template class methods outside class definition

[Martin Magnusson]

I have a templated class, and I want to keep the implementation in a 
separate file, and not in the header file. Shouldn't the code below 
work? When I run the code below through g++ 3.3.1 (Cygwin) I get the 
following message

test.cpp:10: error: syntax error before `::' token
test.cpp:11: error: invalid use of template-name 'vertex' in a declarator
test.cpp:11: error: syntax error before `{' token

--------------------------------------
template<int N>
class vertex
{
public:
  vertex();
  int elements[N];
};

template<int N>
vertex::vertex()    // LINE 10
{
  elements[0] = 0;
}
--------------------------------------
