Thanks, that seems to link after adding `libs "user32"` to my 
`dub.sdl` file.

Though the program built with dub is now crashing at runtime when 
calling `writeln` within the `WinMain` block.

The exception error is:

So it feels that something else is missing or wrong.

Any pointer would be helpful :)
