I wanted to share a positive experience with the few ones still stuck with a 32 bit environment, the MinGW project permits a straightfoward minimalistic setup.
The project is moving to OSDN.net: https://osdn.net/projects/mingw/releases/
..with your browser move into "MinGW Installation/MinGW Get Version ..." and get "mingw-get-0.6.3-mingw32-pre-....zip"
Unzip the folder contents in a new folder, e.g. "c:\mgw", (on Windows it is strongly suggested to avoid spaces in the folders name).
Within the command prompt move into c:\mgw\bin and type:
mingw-get update
mingw-get install bash
mingw-get install mingw-developer-toolkit
(Note that, for certain esoteric reasons, some of the packages installed by mingw-developer-toolkit are MSYS packages, and install into "C:\msys\1.0" or whatever it is configured as virtual /usr directory. If you don't understand this note, don't panic.. just go ahead).
To enable this new environment, prepare a setup batch file, e.g.
set ZCCCFG=/c/z88dk/lib/config
path c:\mgw\msys\1.0\bin;c:\mgw\bin;c:\z88dk\bin;C:\windows\System32;C:\windows;
set MINGW=/c/mgw
set MINGW32=/c/mgw
bash
Another interesting use for this environment is by just adding all the files taken from an official *embeddable* python build (https://www.python.org/downloads/release/python-370/), into "c:\mgw\msys\1.0\bin" to build the MAME emulator.
Most of the eventually missing elements can be installed with the same mingw-get command, just type "mingw-get list" for the description.
MinGW32 - 0.6.3
For the sake of completeness, to build MAME with a self-adjusted mingw32 tool is not easy at all, the 32 bit environment lacks is less complete and different on dealing with threads, so the MAME team still provides a pre-packaged variant of the build tools:

They all should be valid for z88dk as well.
