Thanks, but doesn't work :(
My files contain:

mydll.d:

module mydll;
export extern int i;

mydll2.d:

module mydll;
export int i = 7;

test.d:

import mydll;
import std.stdio;

void main() {
        writefln(i);
}

I can compile the dll, but when I compile test.d, I get the following error: "Error 
42: Symbol Undefined _D5mydll1ii"

It seems that export doesn't work for data, only functions.  If you 
build with -map, you'll see that i is not exported.  I got it working by 
using this .def file:

LIBRARY "mydll.dll"
EXETYPE NT
EXPORTS
D5mydll1ii


Then create the import lib with:
implib /s mydll.lib mydll.dll

/s adds the underscores.


If you use extern (C) the symbols will be a lot simpler to read and 
write, though.  Look at the .map file to see what the actual symbols are.
