 Revision history for Perl extension Time::HiRes.
 
+1.82   [2005-10-06]
+       - CLOCK_REALTIME is an enum value (of the clockid_t enum)
+         in HP-UX (and might be so elsewhere, too), debugged by
+         H. Merijn Brand
+       - include const-c.inc as late as possible (from Randy Kobes,
+         [rt.cpan.org #15552] to avoid undefined usleep() on Win32
+
+1.81   [2005-10-05]
+       - try to be more robust and consistent in the detection of
+          CLOCK_REALTIME and ITIMER_VIRTUAL in HiRes.t: the proper
+         way is
+
+               sub has_symbol {
+                   my $symbol = shift;
+                   eval 'import Time::HiRes qw($symbol)';
+                   return 0 unless $@ eq '';
+                   return exists ${"Time::HiRes::$symbol"};
+               }
+
+         and then use
+
+               &FOO_BAR
+
+         in the test.  All these moves are needed because
+
+         1) one cannot directly do eval 'Time::HiRes::FOO_BAR'
+            because FOO_BAR might have a true value of zero
+            (or in the general case an empty string or even undef)
+
+         2) In case FOO_BAR is not available in this platform,
+            &FOO_BAR avoids the bareword warning
+
+       - wait more (1.5 seconds instead of 0.1) for the CLOCK_REALTIME test
+         but expect the 'customary' slop of 0.20 instead of 0.25
+       - fixed inside a comment HAS_POLL -> TIME_HIRES_NANOSLEEP
+       - at the end of HiRest.t tell how close we were to termination
+
+1.80   [2005-10-04]
+       - Gisle noticed a mistake (using HAS_NANOSLEEP) in 1.79
+
+1.79   [2005-10-03]
+       - try nanosleep for emulating usleep -- may help in some weird
+         embedded realtime places which have nanosleep but neither usleep
+         nor select nor poll (doesn't have to be weird embedded realtime
+         place, though -- in many places usleep is nanosleep anyway)
+       - try poll for emulating usleep -- this may help some obscure/old
+         SVR4 places that have neither usleep nor select
+       - a redundant test guard in HiRes.t
+
 1.78   [2005-10-03]
        - ITIMER_VIRTUAL detection in HiRes.t had problems (that we cannot
-         in the general case fail already at 'use' is suboptimal)
+         in the general case fail already at 'use' phase is suboptimal)
        - fixes to the documentation of clock_gettime() and clock_getres()
