--- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> ---
I was concerned this would be an ABI change for 32-bit targets, but libstdc++
already ensures that std::streamoff is a 64-bit type even when ::off_t isn't.
So now I think building it with large file support should not change the type
of anything in the libstdc++ API or the exported ABI.
