The result of the Microsoft __uuidof operator must be considered a global lvalue during constant expression evaluation.
Otherwise we would get this error in C++11 mode (because of a recent change):
error: non-type template argument of type 'const _GUID *' is not a constant expression
For code like:
template <const GUID* g = &__uuidof(struct_with_uuid)>
class COM_CLASS { };
