You may want to spearhead the effort to get Win32 support of
MSVC into D, if you care enough about it. Rainer has done most
of the work, you'd just have to turn his patches into pull

add some polish:

Let me see what I can do for time. There's the above, it's also
possible to link mixed coff and omf with jwlink
(http://www.japheth.de/JWlink/JWlink.htm).
There's a couple of paths and while win32 isn't leading edge, I
think enhancing it is a worthwhile project for lesser lights like
myself.
