- 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.
