Well, BFD uses stdio, so I think the relevant issue here is that fseek
takes a long argument and ftell returns a long argument.  Both
actually could use unsigned long, except that ftell returns -1 as an
error indication.  But historically they use long, and no doubt there
is code somewhere in the library which checks whether they are
negative.
