  Modified:    support  rotatelogs.c
  Log:
  Axe some warnings in rotatelogs which came when the program was
  converted to use APR.  The behaviors of apr_file_read() and
  apr_file_write() weren't taken completely into account.
  
  But note: In a couple of places the check "nRead < 0" was removed.
            While that is meaningless with APR and hasn't done anything
            useful in a long time, in Apache 1.3 days it was essentially
            a check for read-failed-with-EINTR.  Apparently a rotation
            would occur if the read was interrupted by a signal.  That
            function has been lost with the APR-ization.
