You need a recent version of dmd, druntime and phobos from github: 
https://github.com/D-Programming-Language

If you have never built these yourself, Digger might be of great help: 
https://github.com/CyberShadow/Digger/releases. It will also fetch these 
from github and download tools needed for building. Digger doesn't know 
about COFF32 yet, though.

Then build druntime inside its directory:
make -f win64.mak MODEL=32mscoff "CC=\"%VCINSTALLDIR%\bin\cl.exe\"" 
target unittest

and phobos:
make -f win64.mak MODEL=32mscoff "CC=\"%VCINSTALLDIR%\bin\cl.exe\"" 
"AR=\"%VCINSTALLDIR%\bin\lib.exe\""

Add a configuration section [Environment32mscoff] to your sc.ini and add 
options matching these:

https://github.com/D-Programming-Language/dmd/blob/master/ini/windows/bin/sc.ini#L84

Building is done with option -m32mscoff instead of -m32/-m64.
