I'm guessing this is a mismatch between object formats. By default, DMD
will create libraries in the OMF format, for 32bit platforms. For 64bit
it will create libraries in the COFF format. The OMF format requires the
Optlink linker, shipped with DMD. COFF requires the linker from the
Microsoft tool chain.
It's also possible to output libraries in the COFF format for 32bit
platforms, using the -m32mscoff flag.

I'm not very familiar with Windows. That last part of the question looks
a generic Windows question which is not specific to DWT. I recommend
asking in the "learn" forum/group or you could look have a at the build
script for DWT , which successfully builds and links the snippets.
Note also that the command for Optlink was renamed recently from "link"
to "optlink" (I think), to avoid conflicting with the Microsoft linker.
I recommend using the compiler when linking.
