hangs in 20181129 snapshot hopefully fixed

Corinna Vinschen-2
I pushed a patch and uploaded a 20181201 developer snapshot to
https://cygwin.com/snapshots which hopefully fixes all observed problems
related to the new extensible clock implementation in the 20181129
snapshot.

Basically it should fix clock hangs, as well as a dumb thinko in the
Vista-only implementation of CLOCK_MONOTONIC_COARSE:

In fact, despite its name, Windows' GetTickCount64() does not return
clock ticks as GetTickCount does.  Rather, it returns milliseconds since
boottime, supposedly biased (aka "suspend time taken into account").
So it's not the best fit for CLOCK_MONOTONIC_COARSE, but without a
working QueryUnbiasedInterruptTime function...(*)

Please test.


Thanks,
Corinna

Drop Vista Support? (Was: hangs in 20181129 snapshot hopefully fixed)

Vista extended support ended 18 months ago; standard support 5 years before; all
browsers but Opera and Lunascape (and IE9 on Vista SP2) dropped support for
Vista and XP 6 months ago or earlier; estimates of remaining Vista users are an
order of magnitude less than XP users:

W10 ~ W7 ~45% each >> W8.1 ~ XP ~5% each > W8 ~1% > Vista ~.3-.6% or 1/166-333
systems * setup exe download annual unique IP count?

Does anyone do regular analysis of sourceware access logs to justify support?
What do the sourceware setup exe download and/or mailing list user agent strings
tell you?

N.B. W7/2008 extended (security) support ends in just over a year.
     Start migrating those systems to VMs behind firewalls.
     MS describes this as $100G opportunity (AKA user cost)!

For what it's worth:
Vista does not even rise above the noise at
https://store.steampowered.com/hwsurvey/Steam-Hardware-Software-Survey-Welcome-to-Steam
and is just barely present at
https://netmarketshare.com/operating-system-market-share.aspx?id=platformsDesktopVersions

If I were still supporting Vista on anything, I'd be thinking
seriously about dropping it like a stone.

Assuming the access statistics have any relevance, we get roughly this:

  W 10   69.8 %
  W 8.1   5.4 %
  W 8     0.7 %
  W 7    23.9 %
  Vista   0.2 %

Time to move on, I guess.  There's Linux, too...
