* libio/ftello.c (ftello): Don't subtract save_end - save_base if pos is _IO_pos_BAD. * libio/ftello64.c (ftello64): Likewise. * libio/iofgetpos.c (_IO_new_fgetpos): Likewise. * libio/iofgetpos64.c (_IO_new_fgetpos64): Likewise. * libio/oldiofgetpos.c (_IO_old_fgetpos): Likewise. * libio/oldiofgetpos64.c (_IO_old_fgetpos64): Likewise. * libio/ioftell.c (_IO_ftell): Likewise. Cast to long int instead of off_t when checking for overflow.
