is there a historic C++ ABI which puts the vtable at offset 8 in struct
plus (after the fields from struct base)? This must have been before
the Itanium C++ ABI.
GCC 2.95 on i386 produces such layout.
Was it possible to generate it with later compilers? The GCC 3.0
release notes say that a new C++ ABI was implemented. Was there really
no backwards compatibility?
