[cpp] define extern for templated class

[ibilon]

Trying to define an extern for a templated class.

For instance, std::vector (not specific to this class):

class Test {
    public static function main() {
        var i = cpp.Pointer.fromRaw(Vector.getIntVector());
        i.ptr.reserve(1);
        i.ptr.reserve(2);
    }
}

@:include("vector")
@:native("std::vector")
extern class Vector<T> {
    @:native("new std::vector<int>")
    public static function getIntVector() : cpp.RawPointer<Vector<Int>>;

    public function reserve(_:UInt) : Void;
}

gives:

./src/Test.cpp: In static member function ‘static void Test_obj::main()’:
./src/Test.cpp:29:55: error: type/value mismatch at argument 1 in template parameter list for ‘template<class T> class cpp::Pointer’
 HXLINE(   3)  HX_VARI( ::cpp::Pointer<  ::std::vector >,i) = ::cpp::Pointer_obj::fromRaw((new std::vector<int>()));

because

HX_VARI( ::cpp::Pointer<  ::std::vector >,i)

should be

HX_VARI( ::cpp::Pointer<  ::std::vector<int> >,i)
