I think the better thing to do is /DLL, but still I got these errors:
> dmd -of=dll.dll -betterC -L=/DLL -m32mscoff dll.d
lld-link.exe: error: <root>: undefined symbol: __DllMainCRTStartup at 12
lld-link.exe: error: undefined symbol: _MessageBoxA at 16
>>> referenced by dll.obj:(_Test at 0)

Error: linker exited with status 1

If I do /SUBSYSTEM:CONSOLE I get:
> dmd -of=dll.dll -betterC -L=/SUBSYSTEM:CONSOLE -m32mscoff dll.d
lld-link.exe: error: entry point must be defined
Error: linker exited with status 1

If I add /ENTRY:DllMain to that I get:
> dmd -of=dll.dll -betterC -L=/SUBSYSTEM:CONSOLE -L=/ENTRY:DllMain -m32mscoff dll.d
lld-link.exe: error: undefined symbol: _MessageBoxA at 16
>>> referenced by dll.obj:(_Test at 0)

Error: linker exited with status 1
