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(): http://msdn.microsoft.com/en-us/library/windows/desktop/ms724451%28v=vs.85%29.aspx 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)?Thread Next
