More seriously, in my informal exchanges I don't use C++0x anymore, it

Not IMO. It's just a placeholder name.

It already has virtual functions, so it shouldn't affect the size of
the object.
But it does, even if at the moment I don't know *exactly* why.

-fdump-class-hierarchy might help.

In any case abi_check fails because of the size increase :(

Using an inline namespace is probably the way to go.
