     . test/tisys.c
       test/trsys.c: Change pathname of "isys.h" and "rsys.h" to make the

       of installed ones in case the package is not installed yet on the target
     . Added GCC format attribute to pdip_send(), isystem() and rsystem()
       to detect format errors at compilation time
     . Bug fix: The value of the status returned by isystem()/rsystem()
                reflects the Linux rules after a better
                understanding of the content of $? shell variable
     . PDIP:
        . Increased test code coverage for pdip_util.c
          (total for PDIP is 83.4% lines covered as more error branches
          difficult to enter in are added with new APIs)
     . ISYS:
         . Added PDIP_FLAG_RECV_ON_THE_FLOW in the configuration of the PDIP
           object to receive the data on the flow from verbose applications

               one shot)
             . Added buf_resize_increment field
          . Bug fix and redesign of pdip_recv():
             . When a timeout is passed, suppressed the internal read
               reiterations: any read data is immediately returned to the user.
             . If PDIP_RECV_ERROR is returned, there are no longer received
               data in the buffers
             . If there are outstanding data, they returned immediately if
               a read request without regex is invoked

            to flush was completely wrong !!!
