Oops. Essentially with dmd -c without -i.

In my setup make decides which file to (re)compile. Just found 
that dmd has the option -makedeps which resembles gcc's -M but 
theres no -MM to excluded dependencies from system files. Also 
gcc -M/-MM does not compile while dmd always generated object 
file(s), too. Is there any way to stop this object file 
generation?
