- is requires --enable-64-bit-bfd A 32-bit BFD has a 32-bit signed file_ptr (limiting SEEK_SET to files up to 2gb). I think the only robust way of handling files larger than that 2gb is to require a 64-bit file_ptr (and hence --enable-64-bit-bfd).
It seems to me that we should try to avoid confusing whether the target is 64-bits with the size of a file pointer on the host.
Admittedly the issue is confused now, because file_ptr is typedefed to be bfd_signed_vma. But we don't need to perpetuate the confusion. I think we should define file_ptr to be off_t or off64_t, and then consistently use ftello or ftello64 and friends if they are available.
So I guess I would like to see a bit more to your patch--change the definition of file_ptr, too. Despite the comment, we know how to set the type based on host definitions tested by autoconf--see, e.g., the handling of BFD_HOST_64_BIT.
