This update will be on my Cygwin packaging to do list this weekend!

Please note the longish list of build prereqs for this Cygwin package in the 
Cygwin source package summary:

        https://cygwin.com/packages/summary/gettext-src.html

and Cygwin build script:

        https://cygwin.com/cgit/cygwin-packages/gettext/tree/gettext.cygport

and the longish list of patches applied in the build script:

        https://cygwin.com/packages/x86_64/gettext-src/gettext-0.22.5-1-src

(and the patch history there), all available in the build repo:

        https://cygwin.com/git/?p=git/cygwin-packages/gettext.git

many derived from Fedora due to policy and the previous maintainer's 
affiliation, and our need to also provide a Mingw64 cross-build release for 
native MS Windows cross-toolchain to build a few native MS Windows tools 
required for Cygwin.

[Feedback welcome on any or all of these patches, scripts, etc. and adoption or 
adaption by upstream projects ;^> Cygwin build scripts nicely skip patches no 
longer required with "already applied"!]

It looks like it may be time to ping the libunistring (also libxml2) maintainers 
to provide upgrades to newer versions available, or consider 
--with-included-..., and I should look at releasing an updated ncurses package 
with the latest ~weekly release soon (but Cygwin/Windows changes were made which 
need consideration, evaluation, and testing, before building against that).
