For code reusability the forth-c bindings have been advanced during the
big mol-openbios merger and there is support written in C for HFS and
HFS+ in the tree. Once the tree works fine again for all builds it
should be easy to add for example grub-fs bindings to openbios to reuse
grub's filesystem drivers.
