I'll fix.

I did think about that, yes. However, I didn't figure out a satisfactory 
way to solve it. The problem is that WriteFile, on GNU Make < 4, results 
in a $(shell) call, which seemed worse than a chained call to echo, when 
we already is in a shell command line in a recipe. I wasn't too keen on 
creating a WriteFileInRecipe version either. So I couldn't figure out a 
way to do that that I was happy with. But I'm open to suggestions (or 
even better, working code :-)).
