be defined in <unistd.h> have been moved into a separate header file
  <sys/clib2_net.h> which, for backwards compatibility, can be include
  from within <unistd.h> if the preprocessor symbol __USE_CLIB2_NETLIB
  is defined early on. Eventually, <sys/clib2_net.h> should be removed
  from the general header files and become a local library build header
  file altogether. Note that in this case you would have to build your
  own software using common TCP/IP SDK header files.
