RFC: Give notice of dropping support for Windows NT4?
Message ID:
Building perl with VC++ 2013 emits a warning that a function we use to
determine the OS, GetVersionEx(), is now marked as deprecated and may
be changed or removed in future versions.

In searching for alternatives (e.g. IsOS(), VerifyVersionInfo()) I
noticed that they are seemingly all identified by current MSDN
documentation as being supported from Windows 2000 only. I then
noticed that it says the same for GetVersionEx():

So it looks like MSDN has dropped all mention of NT4 since I'm sure
GetVersionEx() was supported on that OS.

Rather than struggle to find a GetVersionEx() alternative that really
is supported on NT4 (I've no idea off-hand whether IsOS() or
VerifyVersionInfo() are) -- and then struggle even more to find an NT4
machine to test the changes on! -- has the time now come to give
notice (in 5.20) that we intend to remove all NT4 support code from
5.22 (i.e. remove it from some 5.21.x)?
