Right, I think it will be hard or impossible to remove the link-time
dependency, but the stubs should be dead code if no file streams are
ever actually used.

Regarding the standard, I don't know for sure but I would guess this is
too much of a platform/implementation specific issue.

I think that is the whole point of libgloss, quoting
