This very page says for /vd2:

"Allows you to use dynamic_cast Operator on an object being constructed.
For example, a dynamic_cast from a virtual base class to a derived
class."

which is exactly what gtkmm does, IIRC (although I'm not sure where, and
it seems not to be mentioned in the bug). This is why /vd2 is required
for applications using gtkmm.

/vd2 was introduced with Visual Studio 2005.

I don't think so. But feel free to try out.
