GetProcessGroupAffinity error with cygwin 3.1.0-1

GetProcessGroupAffinity error with cygwin 3.1.0-1

[cygwin]

I upgraded to cygwin 3.1.0-1. This works fine on Windows 10. But on Windows Server 2008 this results in the following error message when starting any cygwin process:

The procedure entry point GetProcessGroupAffinity could not be located in the dynamic link library KERNEL32.dll

Is Windows Server 2008 not supported anymore?

Thanks and regards,
Rene

Windows Vista/Server 2008 is still supported, but nobody is actually
testing on it.  No surprise I hope, given the microscopic number of
users on these systems.

Windows Vista/Server 2008 is still supported, but only barely so.
Official support for Vista ended a while ago, official support for
Server 2008 with Service Pack 2 will end in less than a month,
2020-01-14 to be exact.  I'm planning to draw a line in 2020
which will end Cygwin support as well.

Having said that, until 14th of January we're certainly supporting
Vista/2008.  We just failed to notice that the GetProcessGroupAffinity
and GetThreadGroupAffinity functions are missing on Vista/2008.

I'll upload a fixed Cygwin 3.1.1 release pretty soon.

I pushed a patch

https://sourceware.org/git/?p=newlib-cygwin.git;a=commitdiff;h=26cc7769b4b5

I also created a developer snapshot.  Please test the latest Cygwin DLL
from https://cygwin.com/snapshots/


Thanks,
Corinna

I don't quite get the relevance of this list.  We use lots of functions
in Cygein only available in later Windows versions.  Cygwin failed to
load these functions dynamically rather than having them linked in
statically, that's all.

Thank you Corinna for diagnosing and fixing this glitch.  I must have glossed 
over the Windows version matrix for these functions while I was implementing on 
top of them.  Another thing to keep in mind for future work.
Cheers & Regards,

Great, thanks for testing.  Expect a Cygwin 3.1.1 package soon.

Hi Corinna,

the developer snapshot works fine on Windows Server 2008! :-)

Thanks a lot,
