On Windows, when compiling as 32-bit, the compiler makes use of the 
OPTLINK linker that ships with it. OPTLINK only supports OMF. So you can 
compile a C library with dmc (which also uses OPTLINK) or you can take a 
library in COFF format and run it through an object converter (like 
coff2omf or Agner Fog's Object Converter[1]) to convert it to OMF.

When compiling with DMD as 64-bit, the compiler makes use of the Visual 
Studio toolchain, so you can use 64-bit COFF libraries out of the box 
after you install the VS tools.

If you are linking with the import library instead of a static library, 
the same idea applies. But in that case you can run a tool like 
coffimplib on the DLL to create an import library in OMF format, then 
link with it.

Both coff2omf and coffimplib are available, along with other useful 
utilities, as part of the Digital Mars Extended Utility Package [2] 
which is available for sale at [3].

This problem does not exist on Linux or Mac as DMD uses the GCC backend 
for those platforms.
