If you look at the all.sh file, it gives some hints:

# COM client/server example

$(DMD) -c dserver -release $(DFLAGS)
$(DMD) -c chello $(DFLAGS)
$(DMD) dserver.obj chello.obj uuid.lib ole32.lib advapi32.lib kernel32.lib user32.lib dserver.def -L/map
$(DMD) dclient $(DFLAGS) ole32.lib uuid.lib


It looks like the server example needs uuid.lib, ole32.lib, advapi32.lib kernel32.lib, and user32.lib.

The client seems to need ole32.lib and uuid.lib.
