-   FIXME: Note that t_addr is a bfd_vma, which is currently either an
-   unsigned long or unsigned long long, determined at configure time.
-   If t_addr is an unsigned long long and sizeof (unsigned long long)
-   is greater than sizeof (unsigned long), then I believe this code will
-   probably lose, at least for little endian machines.  I believe that
-   it would also be better to eliminate the switch on the absolute size
-   of t_addr and replace it with a sequence of if statements that compare
-   sizeof t_addr with sizeof the various types and do the right thing,
-   which includes knowing whether or not the host supports long long.
