That should work as is. Some ideas:

- you might have another sc.ini in the working directory or your HOME 
directory which is picked up before the one alongside dmd.exe

- for historic reasons LINKCMD64 setting/environment variable might also 
be used, maybe you have set this elsewhere in your sc.ini

If you run dmd with option -v, it will show the used sc.ini and the 
command line used to call the linker.
