- NB: We really cannot compare sm_classInfo directly in IsSameClass(),
- but instead call sm_instance->GetClassInfo(). The former technique
- broke at least on GCC 4.2 (but worked on VC8 shared build).
+ Even though C++ RTTI would be fully available to use, we'd have to to
+ facilitate sub-type system which allows, for instance, wxAny with
+ signed short '15' to be treated equal to wxAny with signed long long '15'.
+ Having sm_instance is important here.
