  libstdc++-v3/libsupc++/typeinfo.

  Anything defined in the ABI docs should be pretty stable.

  To find the base classes, look at the typeinfo for the class, which will be
abi::__class_type_info or one of its derivatives as specified in the ABI doc
section 2.9.5; the derived types have pointers to (one or more) base class
typeinfos.
