Yes, I think so.  The left overs of the linux/unix library were done 
relatively later (first baseunix was done, and everything was 
migrated),   and since the initial libc implementation of baseunix 
didn't introduce FILE *, it was logical to maintain the signatures.

Jonas  might even have started using the libc port for Darwin at that 
point (IIRC about half an year after the big bang), I can vaguely 
remember him helping me with some of those leftover  unix functions, 
which had some issues (iirc clone() usage and problems with a function 
call that had a deviation way of handling parameters (PIPE?)) .  Darwin 
and FreeBSD shared quite a lot of pedigree back then.

So it could even have been Jonas' decision to maintain the signatures, 
not mine.
