/* second_e.c, a second routine using the real-time-clock interface of the
   C standard library.
   This is a valuable port for embedded systems because a real-time-clock 
   is usually available, and the benchmark permits one to test the 
   CPU core on a prototype to see if it is well-tuned to the memory.
   Note that on some OSs clock() returns wall-time ticks since reset.  On 
   others, (such as OS-9000) it returns the process's CPU time utilized since 
   reset.  By convention, if clock() returns -1, it is not implemented.
