Hi, This is a simple patch, the FIXME was not fixable before due to the nonexistence of split wchar types in the BuiltinType::Kind enum. clang has had types like WChar_S for quite some time now so it should simply be a matter of querying the underlying BuiltinType's signedness which is what this patch should do.
I cannot seem to write a meaningful test. If one is needed, a pointer would be nice... -- David Majnemer
