+C void speed_cyclecounter (unsigned int p[2]);
+C
+
+C The rpcc instruction returns a 64-bit value split into two 32-bit fields.
+C The lower 32 bits are set by the hardware, and the upper 32 bits are set
+C by the operating system. The real per-process cycle count is the sum of
+C these halves.
+
+C Unfortunately, some operating systems don't get this right. NetBSD 1.3 is
+C known to sometimes put garbage in the upper half. Whether newer NetBSD
+C versions get it right, is unknown to us.
+
+C rpcc measures cycles elapsed in the user program and hence should be very
+C accurate even on a busy system. Losing cache contents due to task
+C switching may have an effect though.
