Yes, I suggested Bash for Windows only for bleeding-edge MS-Windows 
developers. For non-bleeding-edge, ezwinports and Cygwin are better 
choices. As I'm sure you know the tz project has always assumed a 
POSIX-like environment and there's unlikely to be a native MS-Windows 
port any time soon, so some set of non-Microsoft tools will be needed 
for MS-Windows developers who don't want to be on the bleeding edge.

One other porting note that we ran into behind the scenes with 2016g: to 
generate a distribution tarball exactly in the same format of the 
standard distribution, your tar needs to support options like 
--numeric-owner. For example, because macOS bsdtar lacks these options, 
although it generates working tarballs these tarballs aren't 
byte-for-byte identical to the distributed tarballs. This is important 
for those who need reproducible builds.
