[tz] iana build failures on Windows

[Manuela Friedrich]

Hello Paul, 

Unfortunately we cannot move to gnu make.
So the earlier you get to cut a new release the better!

Thank you!

Regards
Manuela Friedrich

Thanks for checking. I installed the attached. This should appear in the next release.

I hope we don't need a new release urgently merely due to this issue. 
Developers building on MS-Windows can use use GNU Make (via WSL, Chocolatey,  MinGW-w64, etc.) and if nmake has a serious issue like this one I can't help but wonder whether it has other lurking issues we don't know about (plus, 'make check' is buggy even with this patch); so I might suggest GNU Make anyway. If there's some reason developers can't use GNU Make, they can use the first attached patch in the meantime; it's just one line.

There's a good chance we'll need a new tzdb version reasonably soon for some more-urgent reason (Paraguay, say), so this is a temporary situation.
