Log Message:
Update to 1.9706:

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
	- [internal] slightly cleaner building of $DEFINE in Makefile.PL,
	  should avoid double/conflicting -D flags

1.9704	[2007-01-01]
	- allow 10% of slop in test #14 (testing difference between
	  CORE::time() and Time::HiRes::time()), there seem to be often
	  transient failures from Perl smoke builds on this test
	- small pod tweaks

1.9703	[2006-12-08]
	- use int main(int argc, char **argv) consistently in Makefile.PL,
	  should help with
	  [rt.cpan.org #23868] nanosleep not detected under Mac OS 10.3.9 starting with \ 
Time::HiRes 1.96
	- if someone still has the locale-broken Perl 5.8.0,
	  suggest that they upgrade their Perl

1.9702	[2006-12-06]
	- restore the -DATLEASTFIVEOHOHFIVE, Win32 needed it still

1.9701	[2006-12-04]
	- upgrade to ppport.h 3.10_02
	- remove the -DATLEASTFIVEOHOHFIVE
	- use the ppport.h PL_ppaddr, PL_statcache, PL_laststatval
	- use the ppport.h aTHXR for calling Perl stat()
	- switch into four-digit version since 2.0 is coming up
	  awfully fast but not feeling like a major rewrite

1.97	[2006-11-30]
	- 1.95 broke building in Win32 (since pp_stat is not exported),
	  figured out how to call an op directly in 5.005 (use Perl_ppaddr
	  instead of PL_ppaddr)
	- backport to Perl 5.004_05  (requires using statcache
	  and laststatval instead of PL_statcache and PL_laststatval)
	  (also checked to work in 5.005_04, 5.6.1, and 5.8.8 with threads)

1.96	[2006-11-30]
	- 1.95 broke builds for threaded Perls, rt.cpan.org tickets:
	  [rt.cpan.org #23694] Time::HiRes fails tests on Solaris and Perl 5.6.1
	  [rt.cpan.org #23712] Time-HiRes 1.95 Fails make on AIX 5.2 with Perl 5.8.8
	  [rt.cpan.org #23730] Time::HiRes 1.95 fails make on MacOS X 10.3.9/perl 5.8.8
	- use main() prototype consistently in Makefile.PL

1.95	[2006-11-29]
	- integrate core change #29180: Silence VC++ compiler warnings
	  from Steve Hay
	- do not use PL_ppaddr in stat() because that is not available
	  in Perl 5.005_04
	- regenerate fallback/*.inc for older Perls without
          ExtUtils::Constant because of d_hires_stat, resolves
	  [rt.cpan.org #23694] Time::HiRes fails tests on Solaris and Perl 5.6.1
	- Make Makefile.PL more defensive against false PERL_CORE

1.94	[2006-10-16]
	- file timestamps oddities seen: the atime and mtime
	  can be out of sync (modify first and read second can leave
	  atime < mtime) and mtime can be subsecond while atime is not.
	  So make the test more forgiving.

1.93	[2006-10-15]
	- the ualarm() tests (34-37) assumed that ualarm(N)
	  could never alarm in less than N seconds, widened
	  the acceptable relative range to 0.9..1.5.  Addresses
	  [rt.cpan.org #22090] and [rt.cpan.org #22091].

	- skip the stat() tests in cygwin and win32, because
	  if run on FAT the timestamp granularity is only 2 seconds.
	  Any good way to detect (cygwin or win32) whether we are
	  being run on NTFS or anywhere with better timestamps?
	  Addresses [rt.cpan.org #22089] and [rt.cpan.org #22098].

1.92	[2006-10-13]
	- scan for subsecond resolution timestamps in struct stat,
	  some known possibilities:

	  (1)  struct  timespec st_atimespec;
                                st_atimespec.tv_nsec;
	  (2)  time_t  st_atime;
	       long    st_atimensec;
          (3)  time_t  st_atime;
               int     st_atime_n;
	  (4)  timestruc_t st_atim;
                           st_atim.tv_nsec
	  (5)  time_t  st_atime;
               int     st_uatime;

          If something like this is found, one can do

	    use Time::HiRes;
	    my @stat = Time::HiRes::stat();

	  or even override the standard stat():

	    use Time::HiRes qw(stat);

          to get the stat() timestamps

	    my ($atime, $mtime, $ctime) = @stat[8, 9, 10];

	  with subsecond resolution (assuming both the operating
	  system and the filesystem support that kind of thing).

	  Contributions for more systems (especially non-UNIX,
	  e.g. but not limited to: Win32, VMS, OS/2) gladly accepted.
	  (also more UNIX variants welcome: HP-UX? IRIX?)

	  Thanks to H.Merijn Brand, John Peacock, and Craig
	  Berry for brave beta testing.

1.91	[2006-09-29]
	- ualarm() in SuSE 10.1 was overflowing after ~4.2 seconds,
	  possibly due to a glibc bug/feature (suspected overflow at
	  2**32 microseconds?), workaround by using the setitimer()
	  implementation of ualarm() if either useconds or
	  interval > 999_999 (this case seems to vary between systems:
	  are useconds more than 999_999 for ualarm() defined or not)
	  Added more ualarm() tests to catch various overflow points,
	  hopefully no problems in various platforms.
	  (The problem report by Mark Seger and Jon Paul Sullivan of HP.)

1.90	[2006-08-22]
	- tweak still needed for Const64(), from Jerry Hedden
	- get a freshly generated ppport.h
	- update Copyright years

1.89	[2006-08-22]
	- Const64() already appends an 'LL' (or i64), so provide LL and i64
	  forms for the IV_1E[679] (effects Win32 and Cygwin), reported by
	  Jerry Hedden.
	- the Changes entry for 1.88 talked about [IN]V_1[679],
	  missing the 'E'.

1.88	[2006-08-21]
	- clean up the g++ warnings in HiRes.xs, all of them
	  about mixing integer and floating point, introduce
	  constants IV_1E[679] and NV_1E[679]
