Ok, the RDMD distributed with this beta 2 can't even run simple test
modules. That's what happens when people don't test tools on all
systems.
Try running RDMD on this on XP32:
module test;
import std.stdio;
void main()
{
writeln("test");
}
$ rdmd test.d
Nothing happens.
This will work of course: dmd test.d && test.exe
