First working Win64 program!

[Walter Bright]

No, it ain't much, some of it is jury rigged, and there's a heluva lot more work 
to do. But we've got liftoff!

-------------------------------------
import core.stdc.stdio;
extern (C) int main()
{
    puts("hello world\n");
    return 0;
}
-------------------------------------

  dmd -c -m64 hello.d
  cl hello.obj
  hello

hello world!
