+/* machine-dependent cycle counters code. Needs to be inlined. */
+
+/***************************************************************************/
+/* To use the cycle counters in your code, simply #include "cycle.h" (this
+   file), and then use the functions/macros:
+
+                 CycleCounterTicks getticks(void);
+
+   CycleCounterTicks is an opaque typedef defined below, representing the current time.
+   You extract the elapsed time between two calls to gettick() via:
+
+                 double elapsed(CycleCounterTicks t1, CycleCounterTicks t0);
+
+   which returns a double-precision variable in arbitrary units.  You
+   are not expected to convert this into human units like seconds; it
+   is intended only for *comparisons* of time intervals.
+
+   (In order to use some of the OS-dependent timer routines like
+   Solaris' gethrtime, you need to paste the autoconf snippet below
+   into your configure.ac file and #include "config.h" before cycle.h,
+   or define the relevant macros manually if you are not using autoconf.)
+*/
+
+/***************************************************************************/
+/* This file uses macros like HAVE_GETHRTIME that are assumed to be
+   defined according to whether the corresponding function/type/header
+   is available on your system.  The necessary macros are most
+   conveniently defined if you are using GNU autoconf, via the tests:
