there's two library formats: coff and omf. omf is the old one 
that dmd assumes without arguments. coff is the new one with `dmd 
-m32mscoff` or `dmd -m64`.

I would guess one of those libs was built with plain old dmd and 
the other with the other switch.

Might help to just delete the old directories and let it 
redownload and recompile fresh with all the new settings.
