I simply call dmd first.d where first.d contains a small class definition

Still, there is a resulting  executable final.exe.
When running it, I get a windows message telling me that
the application is not 64-Bit compatible

To answer my own post :
the problems vanish when I add a main() method.
question : how do I automagically add a standard main method ?

If you are trying to compile a library, add -lib to make it not require a main method.
