Installation MSYS2
Packages needed
Be very sure to install the packages correct for your architecture. The Guide refers to intel-64bit. The 32bit packages have "i686" as architecture in the name: using them works also perfectly. One can also have both 32bit and 64bit versions on a 64bit machine, for testing and build purposes, since they live in /mingw32 and /mingw64. However beware that applications cannot run together, since the daemons will not work. Run at once either all 64bit or all 32bit apps, do not mix.
One package is msys, the other for mingw64
Use 'pacman -S packagename' to install a package.
Be sure to work in the correct shell: for the 64bit example, launch and work inside MSYS2 MinGW 64-bit
Essential tools:
msys/make
mingw64/mingw-w64-x86_64-pkg-config
msys/pkg-config
msys/tar
For GCC
mingw64/mingw-w64-x86_64-gcc
mingw64/mingw-w64-x86_64-gcc-objc
msys/gcc-libs 9.1.0-2
mingw64/mingw-w64-x86_64-gcc-libs
For Clang + libobjc2
This will install clang and the latest gcc, since clang gets it's headers from that installation... This is the instance of clang usable from MSYS2, you will need to install another later for use under Windows to build libobjc2...

Go to chocolatey software and follow the instructions there:

Here is the script used in Azure CI to build the library, you can follow this pretty easily:

Once this is complete you should have a build of libobjc2 in the build dir.
Patches needed
git master and current release needs no patches
For old releases release, please: shlwapi.h Fix
For a successful build, MSYS2 headers need to be patched. Please apply following proposed fix:
Build instructions
Make
Configure and install as:
./configure --with-layout=gnustep make install
then, remember, to source the script from the respective MinGW shell version, e.g. the 64 bit is in:
. /mingw64/System/Library/Makefiles/GNUstep.sh
