This is fine for 3.3.

This means: "consider register_type to be name of template"

The complaint was:
demo.cpp: In member function `void bus_route::serialize(Archive&, unsigned
int)
':
demo.cpp:180: error: syntax error before `;' token
The minimal example is:
class C {
public:
template<class Archive>
void serialize(Archive& ar)
{
ar.register_type<int>();
}
};
I was not able to test with online comeau, since it seems to fail on
everything, with no error messages. Further, I have failed to find the
relevant text in the standard. The syntax I've used is allowed by the
grammar, but I think there is some text about it as well.
