It probably doesn't work with DMD obj files yet. An update will be 
released in a couple of days, which includes some changes I made, to 
allow asm output from DMD obj files. Agner's made other improvements, 
but I don't know what they are yet.
But it still probably can't convert DMD obj's to coff format. Worth a 
try through.
