optlink is not compatible with Microsoft's linker. So, unless you can somehow 
convert from one format to another, you can't use C code with D code which has 
been compiled by a Microsoft compiler. However, if you use dmc to compile your C 
code, then it links just fine, since it uses optlink as its linker, just like dmd 

Apparently, linking against dlls somehow avoids the COFF vs OMF problem, so that 
would be another way to get around the problem: use a dll for the C code.

Regardless, the fact that optlink unfortunately uses a different format than 
Microsoft's compiler means that you can normally link to C code on Windows 
unless you have all of the source code and can compile it yourself with dmc. 
Maybe someone else knows of a good library format converter though.
