Can't build for Windows on WSL

[znmeb]

I'm trying to build ueforthfor Windows on a Windows Subsystem for Linux Ubuntu 22.04 LTS command line. It found the compiler but seems to be missing a header file dependency:

$ make win32
"/mnt/c/Program Files (x86)/Microsoft Visual Studio/2019/BuildTools/VC/Tools/MSVC/14.29.30133/bin/Hostx86/x86/cl.exe" /c /Foout/windows/uEf32.obj -O2 -I ./ -I out -I "c:/Program Files (x86)/Microsoft SDKs/Windows/v7.1A/Include" -I "c:/Program Files (x86)/Microsoft Visual Studio/2019/Community/VC/Tools/MSVC/14.28.29333/include" -I "c:/Program Files (x86)/Windows Kits/10/Include/10.0.19041.0/ucrt" windows/main.c

Can I build for Windows on WSL? If not, how do I build for Windows on a Windows machine?

Closing this - the new build system is the only thing blocking me at the moment.
