Running all Cygwin "native" and mingw64 cross, x86_64 and i686, desktop 
and CI builds with that patch causes no (obvious) problems and builds 
and checks okay.

To reproduce under Cygwin, see:
https://cygwin.com/cgi-bin2/jobs.cgi?srcpkg=mingw64-x86_64-libidn&status=succeeded&user=Brian+Inglis&id=4390

select package name link takes you to source summary page:
https://cygwin.com/packages/summary/mingw64-x86_64-libidn-src.html

select packaging repository link takes you to git repo:
https://cygwin.com/git-cygwin-packages/?p=git/cygwin-packages/mingw64-x86_64-libidn.git

select playground branch link takes you to:
https://cygwin.com/git-cygwin-packages?p=git/cygwin-packages/mingw64-x86_64-libidn.git;a=shortlog;h=refs/heads/playground

select the tag entry 1.41 and you get a set of sources you can use to 
build under Cygwin, after installing Cygwin, download and run 
setup-x86_64 to install base packages, then rerun setup-x86_64 to select 
packages cygport (which pulls in all the Cygwin build depends) and also 
the DEPEND entries in the cygport (gettext-devel mingw64-x86_64-gettext 
mingw64-x86_64-win-iconv mingw64-x86_64-binutils mingw64-x86_64-gcc-core 
doxygen gengetopt gperf gtk-doc help2man) to install.

To run cygport on this (cygport is a collection of bash scripts):

        $ cygport mingw64-x86_64-libidn.cygport get all check &> log &

move the fix-...-x64.patch out of the way to reproduce the test failures 
in releases 1.39-41.
