Revision history for the Perl extension Time::HiRes.
+1.9708 [2007-10-05]
+ - [rt.cpan.org #29747]: Build failure with perl 5.005_05
+ Fixed by regenerating the ppport.h using Devel::PPPort 3.13.
+
+1.9707 [2007-02-27]
+ - t/HiRes.t failed in Perl 5.6.2,
+ "action is not of type POSIX::SigAction at t/HiRes.t line 318",
+ reported and fixed by Anton Berezin, the reason was faulty
+ use of sigaction() when restoring the old action.
+
+1.9706 [2007-02-25]
+ - with bleadperl in VMS the HiRes.t overrun the maximum number
+ of deferred signals because the libc SIGALRM was not strong
+ enough to interrupt select(), and select() got restarted every
+ time, solution is to use POSIX::SigAction if available.
+ A fix from Craig Berry (not 100% there, but helps).
+ - allow for more measuring noise for ualarm() tests 35..37
+
1.9705 [2007-02-06]
- nanosleep() and clock_nanosleep() detection and use were
quite broken; in Linux -lrt needed; fixes from Zefram
