The i386 DMD can produce Win64 COFF object files which can then 
be linked by the free MSVC toolchain.  Basically you just need to 
install that toolchain and DMD -m64 should just work in my 
experience.  Someone probably has a link handy for the MSVC 
toolchain.  I'm  not sure because I have Visual Studio installed 
for work so I've always already got it installed.
