Just out of curiosity, you can use shell constructs for this, too.

Code:
#!/bin/sh

tac () {
  local line
  if read line; then
    tac
    printf '%s\n' "$line"
  fi
}

for f; do
  tac <"$f"
done
ksh could use print instead of printf; tested with bash. (Using echo is not very robust, but would be compatible even with the earliest Bourne shells. But then, local is a fairly recent addition, isn't it?)
