or helping to get dmd x64 on Windows running (I suggest using MinGW's  
tools for that if possible).

To quote Walter:

"To do 64 bits on Windows requires:

1. 64 bit OMF
2. 64 bit librarian
3. 64 bit generating dmd
4. 64 bit C compiler
5. 64 bit symbolic debug info
6. 64 bit debugger
7. 64 bit C runtime"
