* Turn on large file support in gssftp and rcp (and the rest of the bsd
  applications) using AC_SYS_LARGEFILE.
* The size of off_t might now be greater than that of an int or a long, so
  if we have a "long long" type, assume that format specifiers for it work
  correctly and that we can cast off_t values to long long for displaying
  and logging.
* Check for fseeko(), which takes an off_t, and if we find it, use it
  instead of fseek(), which takes a long and might not handle the full
  range of values.
