Hello, I'm starting to think this may be a problem with minGW.. I have a
template class with an embedded class which I want to make a static
instance member of the template outer class...

#include <vector>
#include <algorithm>
#include "time_stamp.h"
#include "frame_num.h"

using namespace ::std;

template< class M >
class notification
{
time_stamp t_stamp;
frame_num frame_no;
public:
virtual ~notification(){} //must be virtual
class router
{
router(router const &); //no copying
void operator=(router const &);
public:
.............
};
static router r;
};

template< class M >
notification<M>::router
notification<M>::r(); // HERE'S THE PROBLEM REPORTED

The invocacion is:

struct pass_int : public notification< pass_int >
{
int the_int;
};

MinGW, at the line marked above, says...
"expected constructor, destructor, or type conversion before 'notification'"
"expected ';' before 'notification'

Or am I doing something wrong?

Yes, that did it! Thanks a million. Good catch with the parenthesis.
They were a more recent typo, though; got the same problem after
removing them; but 'typename' was it. Hard to get my head around why I
need it, though...
