If it is of interest, below is the makefile I have created for this purpose. It 
has the dependency generation built-in. The part I don't like about it is that 
the -deps option of dmd creates a very large file with all the dependencies, not 
just the one for the .d file being compiled. It is easy to filter out, but there 
is unnecessary IO (something you mentioned as being slow).
