I just downloaded and built DWT following Jacob's instructions at 
the bottom of this page.

I made a 64-bit build, and I had no problem linking via dmd, 
which found the Microsoft linker despite the presence of the 
32-bit linker, optlink, which is in the directory on my path 
where dmd is. Optlink was named link.exe in my version, 2.069.1 
which collides with the name of the Microsoft linker. But if I 
attempt to link from the command line, optlink executes and fails 
on 64-bit libs.

Your link command looks similar to that in the windows 32-bit 
command on the web page above. So you are attempting to run the 
32-bit linker, optlink. I'm assuming this means you attempted a 
32-bit build of DWT as on that page, before attempting to compile 
HelloWorld and link separately. Could you post your exact 
commands to build DWT, to compile HelloWorld and to link 
HelloWorld and the entire linker error message?
