+C void speed_cyclecounter (unsigned p[2]);
+C
+C Get the pentium rdtsc cycle counter, storing the least significant word in
+C p[0] and the most significant in p[1].
+C
+C cpuid is used to serialize execution.  On big measurements this won't be
+C significant but it may help make small single measurements more accurate.
