I think I would disable the built-in extension in both C++11 and C++1y
if we're in ISO mode, and leave it enabled if we're in GNU mode.
I think the ideal behavior for these suffixes would be to treat them as
user-defined literals if a corresponding literal operator is available,
or use the built-in extension if not. But that doesn't need to happen now.
