> How would such a platform without file systems handle #include?

I don't think it would, you'd cross-compile for it on a platform with a file system. I think the parent poster's point was that C is the only option for some ultra low resources platforms and that a conservative approach should be taken to add new features in general. I don't think they were saying that specifically that not having a filesystem is problematic for this particular inclusion.
