druntime is not compiled as `-betterC`, because the entire point 
of `-betterC` is to prevent a dependency on druntime, at least at 
link-time [so C forward declarations and some templates can be 
used by code compiled as `-betterC`].

I'm not sure what you are trying to achieve; you can easily 
cross-compile druntime & Phobos with LDC, see
